Safely and Effectively Using Your Analyzer
Using Your Analyzer
This section discusses the basics of using your analyzer, no matter the specific type of analysis
you wish to perform. First we go over analyzer safety, particularly radiation safety. Using an
X-ray based analyzer safely is very important, and not difficult, provided you read,
understand, and follow these guidelines. Secondly, we outline the startup procedure we
recommend for daily use to ensure that your analyzer is performing properly and at its most
efficient level.
Safely and Effectively Using Your Analyzer
CAUTION Niton analyzers are not intrinsically safe analyzers. All pertinent Hot Work
procedures should be followed in areas of concern.
Radiation and General Safety
WARNING Always treat radiation with respect. Do not hold your analyzer near the
measurement window during testing. Never point your analyzer at yourself or anyone else
when the shutter is open.
Radiation and General Safety
This section covers topics related to radiation safety and general safety when using a Thermo
Scientific Niton XL3 analyzer. At a minimum all operators of the analyzer should be familiar
with the instructions provided in this chapter in order to handle the analyzer in a safe manner.
In addition to reading the information presented on the following pages, Thermo Fisher
Scientific recommends that instrument users participate in a radiation safety and operational
training class.
Radiation Protection Basics
The Niton Model XL3t analyzer contains an x-ray tube which emits radiation only when the
user turns the x-ray tube on. When the x-ray tube is on and the shutter is open, as during a
measurement, the analyzer emits a directed radiation beam - see Figures 1 and 2. Reasonable
effort should be made to maintain exposures to radiation as far below dose limits as is
practical. This is known as the ALARA (As Low as Reasonably Achievable) principle. For any
given source of radiation, three factors will help minimize your radiation exposure: Time,
Distance, and Shielding.
The Niton Model XL3p analyzer contains a radioactive sealed source. Radiation from this
source is fully contained within the device when not in use and allowed to escape through the
measurement window only while the user is analyzing a sample. Radiation emission is
controlled by a shutter. The analyzer emits a directed radiation beam (See Figure 1 and Figure

2) when the shutter is open during a measurement. Reasonable effort should be made to
maintain exposures to radiation as far below dose limits as is practical. This is known as the
ALARA (As Low as Reasonably Achievable) principle. For any given source of radiation, three
factors will help minimize your radiation exposure: Time, Distance, and Shielding.
Time
The longer you are exposed to a source of radiation the longer the radiation is able to interact
in your body and the greater the dose you receive. Dose increases in direct proportion to
length of exposure.
Distance
The closer you are to a source of radiation, the more radiation strikes you. Based on geometry
alone, dose increases and decreases with an inverse-squared relation to your distance from the
source of radiation (additional dose rate reduction comes from air attenuation). For example,
the radiation dose one foot from a source is nine times greater than the dose three feet from
the source. Remember to keep your hands and all body parts away from the front end of the
analyzer when the shutter is open to minimize your exposure.
Shielding
Shielding is any material that is placed between you and the radiation source. The more
material between you and the source, or the denser the material, the less you will be exposed
to that radiation. Supplied or optional test stands are an additional source of shielding for
analysis. A backscatter shield accessory is also available and may be appropriate in some
applications.
Exposure to Radiation
Human dose to radiation is typically measured in rem, or in one-thousandths of a rem, called
millirem (mrem), 1 rem = 1000 mrem. Another unit of dose is the Sievert (Sv), 1 Sv = 100
rem. The allowable limit for occupational exposure in the U.S (and many other countries) is
5,000 mrem/year (50 mSv/year) for deep (penetrating) dose and 50,000 mrem/year (500
mSv/year) for shallow (i.e., skin) dose or dose to extremities. Deep, shallow, and extremity
exposure from a properly used Niton XL3t analyzer should be less than 200 mrem per year,
(2.0 mSv per year) even if the analyzer is used as much as 2,000 hours per year, with the
shutter open continuously. The only anticipated exceptions to the 200 mrem maximum
annual dose are: 1) routine and frequent analysis of plastic samples without use of a test stand,
backscatter shield, or similar additional protective measures, or 2) improper use where a part
of the body is in the primary beam path.
Note NEVER OPERATE THE DEVICE WITH A PART OF YOUR BODY IN THE
PRIMARY BEAM PATH OR WITH THE PRIMARY BEAM PATH DIRECTED AT
ANYONE ELSE.

Also, consider the use of protective accessories such as a shielded test stand or backscatter
shield (or equivalent) when performing routine and/or frequent analysis of any of the
following:
• plastic (or similarly low density) samples,
• thin samples (such as foils, circuit boards, and wires)
• samples that are smaller than the analysis window.

Monitoring your radiation exposure
Individuals can be monitored for the radiation dose they receive by use of radiation dosimetry
devices (dosimeters). Monitoring dose using a dosimeter can be a way of identifying improper
use and at the same time demonstrating proper use. In some locations, dosimetry is required
by regulations and in others it is optional. It is normally required when the user could
reasonably be expected to receive in excess of 10% of the annual dose limit. Thermo Fisher
Scientific recommends that you determine and obey the local regulatory requirements
concerning radiation monitoring of occupational workers.
Two common types of dosimeters are whole-body badges and ring badges. Whole body
badges are often attached to the user’s torso (e.g., clipped to the collar, shirt pocket, or waist as
appropriate). A ring badge is worn on the finger as a measure of maximum extremity dose.
When worn, the specific location of the dosimeter should be that part of the body that is
expected to receive the highest dose. This location will depend on how the analyzer is used
and so it may not be the same for all users. Dosimetry services are offered by many companies.
Two companies offering dosimetry services in the USA and much of the world are:

Note Wearing a dosimeter badge does not protect you against radiation exposure. A
dosimeter badge only measures your exposure (at the dosimeter location).
Pregnancy and Radiation Exposure
International guidance documents (e.g., ICRP Publication 60 and NCRP Publication 116*)
recommend that the radiation dose to the embryo/fetus of a pregnant woman should not
exceed a total of 500 mrem (10% of normal radiation worker limit) during the gestation
period. While this dose limit exceeds the dose limit to a trained operator, pregnant workers
may want to take special precautions to reduce their exposure to radiation. For more
information see the U.S. NRC Regulatory Guide 8.13 "Instruction Concerning Prenatal
Radiation Exposure" which can be found on the resource CD.
* The International Commission on Radiological Protection, ICRP, is an independent
Registered Charity, established to advance for the public benefit the science of radiological
protection, in particular by providing recommendations and guidance on all aspects of
protection against ionizing radiation.
* The National Council on Radiation Protection and Measurements (NCRP) was chartered
by the U.S. Congress in 1964 as the National Council on Radiation Protection and
Measurements.
How to Use the Niton XL3t Analyzer Safely
The Niton XL3t analyzer is designed to be safe to operate provided that it is used in
accordance with manufacturer's instructions. Under conditions of normal use, monitored
operators seldom receive a measurable dose and have not been known to receive in excess of
10% of the annual occupational dose limits (a criteria that would require monitoring under
regulation in the U.S.). In addition to proper use of the XL3t, it is recommended that you
follow these precautions to ensure your safety and the safety of those around you.
Know where the beam is
The primary beam is a directed beam out of the front of the analyzer that can have high dose
rates. The secondary beam, or scattered beam, has much lower dose rates.

Handle and Use with Respect
Avoid holding the front of the analyzer when the x-ray tube is energized and the shutter is
open. Never point the instrument at yourself or anyone else when the shutter is open and the
x-ray tube is energized. Never look into the path of the primary beam.
Follow a Radiation Protection Program
Your organization should establish, document, and follow a Radiation Protection Program.
An example of such a program can be found on the resource CD (provided with the
instrument).
Take Proper Care of your Niton XL3
Keeping your analyzer maintained in good condition will help minimize the risk of accidental
exposure. Mechanical malfunction of the shutter can be avoided by maintaining the
measurement window, as described in the User Guide. This prevents foreign objects from
entering your analyzer

Extremity is defined by the NRC as the hand, elbow, arm below the elbow, foot, knee, or
leg below the knee. Whole Body is defined by the NRC as the head, trunk (including
male gonads), arms above the elbow, or legs above the knee.
*Based on maximum deep dose rate and US exposure limit.
Safe Handling of Samples
As mentioned many times in this chapter, never place any part of your body in the path of the
x-ray beam. There is always a safe way to handle samples whether they are small, irregularly
shaped, or of low density. Never look into the path of the primary beam.
Small Samples
A small sample would be any sample that is smaller than the measurement window. Small
samples present a unique risk because they don’t block the entire beam path. The difficulty
with placing small samples down on a work surface to analyze them is that you may get
readings from the work surface that interfere with analytical results. A test stand is an effective
way of analyzing small samples accurately and safely. Never hold samples during analysis or
look into the path of the primary beam.

Safe Handling of Samples
Irregularly Shaped Samples
Irregularly shaped samples may not allow the proximity button to be depressed, or they may
not entirely cover the primary beam and cause additional scattering. A back scatter shield is a
safe way of reducing your radiation exposure while effectively analyzing an irregularly shaped
sample.
Low Density Materials (such as plastics).
X-rays are attenuated more through denser materials and less through low density materials
such as plastic. This causes higher dose rates in the scattered radiation. If you are frequently
handling low density samples, you should consider the use of test stands, backscatter shields,
or the equivalent.

Primary Radiation
Primary Radiation
Niton XL3t and XL3t GOLDD
Primary radiation is radiation that is produced by the analyzer and emitted out through the
measurement window. Individuals should never place any part of their body in the primary
beam path when the x-ray tube is on. There should always be a sample in contact with the
measurement window when the x-ray tube is on. The sample will absorb most of the
primary-beam radiation unless it is smaller than the instrument's measurement window or of
low density and/or thickness. Caution should be taken when analyzing samples that are small,
thin, and/or low in density as they may allow much more of the primary beam to escape.
In-beam primary radiation dose rates are listed in Table 1-6, 1-7, 1-8, 1-9, and their location
identified relative to the analyzer in Figure 4 as Dose Point C.
Niton XL3p
Primary radiation is radiation that is produced by the analyzer and emitted out through the
measurement window. Individuals should never place any part of their body in the primary
beam path when the shutter is open. There should always be a sample in contact with the
measurement window when the shutter is open. The sample will absorb most of the
primary-beam radiation unless it is smaller than the instrument's measurement window or of
low density and/or thickness. Caution should be taken when analyzing samples that are small,
thin, and/or low in density as they may allow much more of the primary beam to escape.
In-beam primary radiation dose rates are listed in Table 1-6, 1-7, 1-8, 1-9, and their location
identified relative to the analyzer inFigure 4 as Dose Point C.
Secondary Radiation
Under conditions of normal and proper use, individuals can be exposed to secondary (or
"scattered") radiation. Secondary radiation is low-level radiation that emanates from the
sample being analyzed as a result of primary beam radiation scattering in the sample or
primary beam radiation inducing fluorescent x-rays in the sample. Dose points A, A’ and B in
Figure 4 are examples of where you can encounter secondary radiation. The magnitude of this
secondary radiation is sample dependent. Higher density samples such as steel will emit the
lowest levels as they absorb most primary and secondary radiations. Lower density samples
such as aluminum, wood, and especially plastic, will produce higher levels of secondary
radiation.
Niton XL3t and XL3t GOLDD
Secondary radiation dose rates are listed in Tables 1-4, 1-5, 1-10, and 1-11, for a few common
sample types over a wide range of densities.

Deep and Shallow Dose
Niton XL3p
Secondary radiation dose rates are listed in Tables 1-13 and 1-14 for a few common sample
types over a wide range of densities.
Holding Samples
The operator is reminded that one should never hold samples during analysis, doing so will
result in higher than necessary exposure to secondary radiation and could expose the operator
directly to the much higher primary-beam dose rates.
Deep and Shallow Dose
You will find in the tables that shallow dose rates are listed for some dose points. All dose rates
listed in the In-Beam Primary Radiation Tables are deep dose unless they are specifically
identified as shallow dose. Deep dose is dose from penetrating radiation that is delivered to
both skin and underlying tissues and organs and is the type most commonly referred to when
describing external radiation hazards. Occupational deep dose is limited to a maximum of 5
rem (50 mSv) per year in the United States and most countries internationally. Deep dose is
measured at 1.0 cm below the skin surface.
Shallow dose is often referred to as "skin dose" because it is a result of low penetrating
radiation that only interacts with the skin. Shallow dose is limited to a maximum of 50 rem
(500 mSv) per year in the United States and most countries internationally. Shallow dose is
listed for primary in-beam dose points only because the low penetrating radiation that causes
shallow dose is nearly all absorbed by a sample and does not produce any significant secondary
radiation. Shallow dose is measured at a point 0.007 cm below the surface.
Proper and Improper Operation
Storage and Transportation
Storage
Regulations in nearly all locations will require that you store your analyzer locked in a secured
area to prevent access, use, and/or removal by unauthorized individuals. Storage requirements
will vary by location, particularly with regard to storage at temporary job sites or away from
your primary storage location such as hotels and motels and in vehicles. You should contact
your local Radiation Control Authority to identify the specific storage requirements in your
jurisdiction.

Transportation
Niton XL3t and XL3t GOLDD
There are no X-ray tube specific US Department of Transportation (DOT) or International
Air Transport Association (IATA) radiation regulations regarding shipping the Niton XL3t
analyzer. It is recommended that you ship the analyzert in its carrying case and an over-pack
to protect the sensitive measuring equipment inside the analyzer. Do NOT ship the analyzer
with the battery pack connected to the analyzer.
Niton XL3p
For Thermo Fisher Scientific, Niton Analyzers (Niton Analyzers), in the United States, the
government agency that has primary authority and regulations which apply to transportation
is the Department of Transportation (DOT) (Code of Federal Regulations 49 Parts 100 to
185).
In addition, the EPA, OSHA, and the NRC also have regulations that touch on the
transportation of hazardous substances.
The International Air Transport Association (IATA) has recommendations that every major
air carrier has incorporated into their policies for the air transport of hazardous substances.
The enforcement of DOTregulations is carried out by the Department of Transportation, the
Federal Aviation Administration, the Federal Highway Administration, the Federal Railroad
Administration, the Coast Guard, and Customs and Border Protection. State agencies may
also enforce state DOT regulations.
The major aspects of the regulations include:
• "training to recognize hazards and how to safely deal with hazardous substances,
• "classification and identification of packages to inform of hazards,
• "protective packaging to safely transport hazardous materials,
• "hazard communication to inform personnel of hazards in a package,
and
• "incident reporting to inform regulators of incidents.
As part of shipping hazardous substances, you should be trained in:
• "a general awareness and a familiarity with the general provisions of the DOT and hazardous
materials regulations,
• "training that is function specific and be applicable to the daily work performed,
• "the recognition and identification of hazardous substances,
24
Niton XL3 Analyzer User’s Guide
Thermo Scientific
2 Using Your Analyzer
Proper and Improper Operation
• "the specific requirements for functions performed,
• "security measures to keep a package secure.
• "safety issues as related to safe handling and hazard communication.
• "knowledge of emergency response information, self-protective procedures, and accident
prevention procedures.
Employers are responsible for providing the proper training (every three years for DOT) to
employees, testing employee knowledge, and record keeping.
The DOT Hazardous Material Regulations set the criteria for determining the hazard class
and the proper shipping name for hazardous materials. The Hazard Classes as follows:
Class
1. Explosives
2. Gases
3. Flammable and Combustible Liquids
4. Flammable solids, combustible materials, and dangerous when wet materials
5. Oxidizers and organic peroxides
6. Toxic materials and infectious substances
7. Radioactive Materials
8. Corrosive Materials
9. Miscellaneous dangerous goods
Niton analyzers with radioisotopes are Hazard Class 7. The Hazard Class of the material being
transported tells you which Parts of the regulations are required.
A UN number is assigned to each type of hazardous material. It is the letters "UN" followed
by a four digit numerical code, which allows emergency responders to identify the chemical
being shipped. The UN number for Niton analyzers is "UN 2911".
There is also an official name designation for Niton Analyzers called the Proper Shipping
Name. The proper Shipping Name for the Niton Analyzers is "Radioactive material, excepted
package-instruments and articles".
A reportable quantity (RQ) is listed in DOT regulations for each hazardous material (e.g.,
each radioactive isotope). If you are shipping more than the reportable quantity in a package,
that package must be marked clear and legibly with the letters "RQ". The Niton XL3p
analyzer contains a 30 mCi (1.11 GBq) Am-241 source and is therefore considered a
reportable quantity requiring the RQ marking when being transported.
Thermo Scientific
Niton XL3 Analyzer User’s Guide
25
2
Using Your Analyzer
Proper and Improper Operation
Also, the quantity of Am-241 that is used in a Model XL3p Analyzer requires a special form
certification for transport as an excepted package. This Special Form certificate must
accompany the instrument during shipment. Thermo Fisher Scientific will provide the
Special Form certificate for any analyzer with Am-241.”
The type of protective packaging used is dependent on the nature of the material to be
packaged. All packaging must be designed to prevent a release of hazardous material during
normal transportation or storage of the material. The classification of package used for Niton
Analyzers is designated as an "Excepted Package". Always ship the analyzer in its original
plastic case to ensure that the packaging used meets the regulatory requirements for an
Excepted Package.
Shipments of radioactive materials must have proper Labeling and Marking.
Niton analyzers have a Marking requirement (i.e., UN number and RQ if applicable), but not
a Labeling requirement (i.e., diamond shaped hazmat labels), and vehicles transporting these
analyzers are not required to have "Placards".
When reading the DOT regulations, you will find the following information useful.
Thermo Fisher Scientific, Niton Analyzers are shipped:
• "Under the proper shipping name "Radioactive material, excepted package-instruments or

Proper and Improper Operation
Always ship in supplied plastic case, with the case secured against accidental opening. Always
ship with the battery disconnected.
When shipping by air: Ship with the proper IATA marking (See IATA Dangerous Goods
regulations Figure 10.7.8.A), UN 2911, and proper shipping name.
"RQ" marking and "dangerous goods declaration" are required.
When shipping by Ground: Ship under proper marking "UN2911"
"RQ" marking and shipping papers are required (Note: a dangerous goods declaration form
can be used to meet the shipping paper requirement).
A "Dangerous Goods Declaration" can be obtained by the air carrier that you will be using.
Instructions can also be obtained from the same source.
Carefully follow the directions given by the air carrier. Several typed copies will be required.
Shipping papers contain all of the same information as a Dangerous Goods Declaration, but
do not have a specified format for that information.
At a minimum, a properly prepared shipping paper clearly identifies the hazardous substance
by its proper shipping name, hazard class and division, UN identification number, packing
group (if applicable), and total quantity. It also has consigner information, consignee
information, and a shipper's declaration that the package is in compliance with the DOT
regulations.
The elements of hazard warning information are communicated through shipping
documents, packaging markings, and written emergency response information.
The DOT & FAA Hazardous Materials Regulations require the carrier to report all incidents
involving hazardous materials.
An "incident" involves the unintended release of hazardous materials (Am-241), suspected
radioactive contamination, if the general public is evacuated for an hour or more, or the flight
pattern or routine of an aircraft is altered.
For any "incident", contact the Company Radiation Safety Officer or Responsible Party and
the state radiation control program.
Any "incident" needs to reported to the:

Proper and Improper Operation
Leak Tests (Niton XL3p Only)
The Niton XL3p Series analyzer contains a radioactive source that must be periodically leak
tested. The purpose of leak testing is to verify the integrity of the source encapsulation. A leak
test sample is obtained by wiping exterior surfaces of the device with moderate pressure using
a cotton swab, filter paper, or whichever wiping media is supplied by the analysis laboratory.
Leak test samples are then typically analyzed at a laboratory, although some device users have
the equipment and licensed authority to perform this analysis
Unless specified otherwise by your local authority or radioactive material license, the gauge
must be leak tested at intervals not to exceed 6 months. In the US, leak test samples may be
acquired by any end-user, however the analysis of the sample must be performed by an
organization licensed to do so. If you are using a vendor to perform the laboratory analysis of
the leak test sample, they will send you a leak test kit which comes with complete instructions
for performing the test. These vendors will also typically send you a reminder when it is time
to perform the next leak test on your instrument. Please follow the test kit instructions
carefully, and promptly mail the test samples to the laboratory. They will send you a leak test
certificate soon after. Keep one copy of the leak test certificate with the device at all times (i.e.,
in the case) and another copy safely on file.

The Results Screen
The Nominal Seconds Test Duration line shows the number of nominal (source) seconds
elapsing since the initiation of the reading. Nominal seconds are instrument time designed to
compensate for the electronic dead-time that may occur when your analyzer is taking a
measurement, and therefore tend to be a bit slower than real time.
The Mode displays the test mode in use during the measurement.
The Match/No Match line indicates whether your analyzer has found a matching alloy in it's
library for the sample you have measured, and displays the name(s) of any matching alloys
and the Match Number (chi squared deviation).
The Element (left) column shows the elements that have been detected in the sample.
The Concentration Level (central) column shows the concentration levels of the
corresponding elements in percentages.
The Confidence (right) column displays the 2 sigma (95%) confidence interval for the
corresponding elements.
If there are too many elements detected to fit onto a single screen, you can see the balance of
the elements and their results (as in figure 3-16) by pressing the down arrow of the 4-way
touch pad. To see previous results, use the left arrow of the 4-way touch pad. To go forward to
later readings, use the right arrow of the 4-way touch pad.
Match Number
The Match Number is a rating of confidence in the identification of the alloy. The Match
number ranges from 0.0 to 10.0, with 0.0 being a perfect match. Any number greater than
4.0 gives a result of No Match by default, although you can change this match threshold. Any
number less than 2.0 is considered a Good Match, and can usually be brought closer to 0.0
with longer testing times. Numbers between 2.0 and 3.0 can be considered Probable Matches,
and numbers between 3.0 and 4.0 as Possible Matches, often having one or more elements out
of spec.

From the Main Menu, select the System icon, then the Specs icon. The date will be displayed
for verification. If the date is incorrect, correct it prior to proceeding. This can be done by
“Closing” out of the Specs screen and selecting the Date & Time icon. Detailed information
on this procedure is available in Setting the Date and Time.
(Optional) Connect the analyzer to a computer via the included serial cable, USB cable, or
Bluetooth™ wireless module. (Consult “Using Your Analyzer With Your PC” on page 151for
details, if necessary.)
During analysis and detector calibrations, it is important to ensure that the analyzer is not
exposed to strong electromagnetic fields, including those produced by computer monitors,
hard drives, cellular telephones, walkie talkies, etc. Keep a minimum two (2) feet (0.7 meters)
distance between the analyzer and electronic devices.
From the Main Menu, select System Check icon then the Yes button. (Figure 1.)
System Check calibrates the detector and verifies it is operating to specifications. After starting
the process, no further user interaction is required during this operation. When the
instrument is finished performing the check, the unit will show either “System OK” or one of
the failure errors.
If the unit shows a failure error, then perform a second System Check by clicking Recheck. If
the unit still does not show a “System OK,” please contact Thermo Scientific Niton Analyzers
toll-free in the USA at (800) 875-1578, +1 978 670-7460, niton@thermofisher.com, or
contact your local Niton Analyzers representative for assistance.
Figure 41. System Check Menu Path
Thermo Scientific Niton XL3 analyzers are equipped with excitation filters that optimize the
analyzers’ sensitivity for various elements. The “Main Range” filter provides optimum
sensitivity for the elements manganese (Mn) through bismuth (Bi). The “Low Range” filter is
used to optimize the sensitivity for the elements from titanium (Ti) through chromium (Cr).

General Analysis
Note that the main range filter can be used to analyze Ti, V and Cr, but the sensitivity is not
as good as when using the low filter. The "Light Range" filter is available only with He-purged
and GOLDD technology analyzers, and is typically used in light element analysis. The
amount of time that the analyzer spends in each filter position is user definable, but the
default settings should be used unless there is reason to change them. Please note that the
analyzer will continue alternating excitation filters until the user selectable maximum analysis
time is reached or the operator terminates the measurement.
Figure 42. Setting Element Ranges
Verify instrument measurement accuracy using the supplied reference material (RM) supplied
with the analyzer.
Test the factory-supplied reference standard (or other approved check sample) based on a 30s
measurement using main range filter only. If the sample is correctly identified and all major
elements read within calculated acceptance limits (within the low and high values of factory
readings found on the QC sheet, proceed to General Testing Protocol section
If the analyzer reports values outside the acceptance tolerance ranges specified in the tables,
repeat the detector calibration then repeat the reference sample analysis.
If the analyzer again fails to meet the acceptance tolerance ranges specified in the tables, please
contact Thermo Scientific Niton Analyzers or your local representative for assistance.
GENERAL TESTING PROTOCOL
Good surface preparation is essential for obtaining accurate test results. All non- representative
material (e.g., paint, coating, scale) must be removed prior to testing. An approximately
2-inch-square section of surface should be cleaned down to the material to be analyzed. See
the Resource Guide for information on Sample Preparation.

How to Analyze
General Analysis
The analyzer will often display a correct alloy identification and/or accurate chemistry result
before the specified time interval. If the accuracy meets the user’s requirements, it is not
necessary to measure for the full time.
Longer measurements might be necessary if low concentrations of elements must be
determined.
INSTRUMENT QC
Measure the supplied reference calibration check sample AT LEAST once a shift. If correct,
continue work. If incorrect, redo System Check and re-take the past 2 hours of results.
UNDERSIZED OR NON-CONTACT SAMPLES
(Samples that do not make contact with or that do not fully cover the measurement aperture)
For samples that do not fully cover the measurement aperture, increase the testing time by
increasing the time in inverse proportion to the decrease in percentage of aperture covered.
For example: a rod only covers ½ of the aperture, so increase the measurement time by two
(e.g., from 10 to 20 seconds per filter for alloy chemistry).
The best procedure to measure undersized samples is to use the Thermo Scientific Niton
portable test stand (optional), which is shielded to prevent radiation exposure to the operator.
An undersized sample may alternately be measured while lying on another material. Results
may be affected by the signal coming from the underlying material itself. Use only pure
aluminum, pure plastic, or clean wood and employ the Disable Al feature. Use the Tools
Menu, then select Disable Al, and check the underlying surface itself to be sure no metals are
present. Be sure to use the Tools Menu and select Enable Al before testing aluminum alloys.

Analysis Modes
Your analyzer has several Analysis Modes. Which Analysis Mode you should use depends on
the nature of the sample you are attempting to analyze.
General Metals Mode
Use this mode to analyze samples entirely composed of metal alloys. This mode will attempt
to return an Alloy Grade Identification by matching the analyzed composition of the sample
with the nominal composition of alloys in the analyzer's Alloy Grade Library. It will also
return an elemental composition of the alloy as analyzed. Alloy Composition is output by
default in terms of percent of composition by weight.

Precious Metals Mode
Use this mode to analyze samples composed primarily of precious metals. This mode will
attempt to return an Alloy Grade Identification by matching the analyzed composition of the
sample with the nominal composition of alloys in the analyzer's Precious Alloy Grade Library.
It will also return an elemental composition of the precious metal sample as analyzed. Precious
Alloy Composition is output by default in terms of parts per million.
See “Using Precious Metals Mode” on page 82.
Plastics Mode
Use this mode to analyze samples composed primarily of plastic. This mode will return an
elemental composition of the plastic sample as analyzed. Plastic Composition is output by
default in terms of parts per million.

Soils Mode
Use this mode to analyze samples composed primarily of soil and rock. This mode will return
an elemental composition of the soil sample as analyzed. Soil Composition is output by
default in terms of parts per million.
See “Using Soils Mode” on page 84.
Mining Cu/Zn Mode
Use this mode to analyze samples composed of potential metal ore - rock containing high
proportions of metal - and containing Cu and/or Zn. This mode will return an elemental
composition of the ore sample as analyzed. Ore Composition is output by default in terms of
percent of composition by weight.

percent of composition by weight.
See “Using Mining Ta/Hf Mode” on page 86.
TestAll Mode
Use this mode to analyze samples composed of unknown and/or mixed composition, such as
toys and consumer products. This mode will attempt to return a general Material
Identification by comparing the analysis with other general types of materials. It will select the
proper sub-mode for analysis and return an elemental composition of the sample as analyzed.
Material Elemental Composition is output by default in terms of parts per million.
See “Using TestAll Mode” on page 86.
TestAll Geo Mode
Use this mode to analyze powder, mineral, and ore samples without first determining whether
the samples would best be analyzed with Mining or Soil Mode. This mode uses both the
Compton Normalization calibration (Soil) and the Fundamental Parameters calibration
(Mining) to determine whether the soil calibration is acceptable or whether the total metal
content is too high for Compton mode. It will then return an elemental composition of the
sample as analyzed. If the sample can be analyzed via soil mode, then the analyzer will display
results from both Soil and Mining Modes in one unified list. If both calibrations contain the
same element, then the mode that has the lower detection limit will be displayed. Material
Elemental Composition is output by default in terms of both parts per million (mg/kg) and
percent of composition by weight, with 0.10% being the cutoff point.
Note Due to the nature of this mode, your analyzer will only use factory calibrations. User
modified Cal Factors will not be available.

Common Operations
Metal Sample Prep
Up until recently, sample preparation was not a big worry for XRF metals analysis, as the
LOD of the analyzer was seldom low enough for any but the most heavy contamination to be
intrusive; but recent developments such as He-purged analysis have brought analysis to a level
where even light surface contamination can skew an analysis.
You should always prepare your samples before analysis, especially when using He-purged
analysis, as these analyzers will see even trace amounts of contaminants. Oils from fingerprints
and other body contact, lint, oxidation materials, and abrasive materials used in cleaning can
all skew readings if not removed. Sample preparation is simple and not time consuming, and
usually well worth the effort.
The following is a list of problems that need correction before testing:
• Oxidation or Rust may produce an increase or decrease in one or more element test
values unless we remove the rust or oxidation and expose the raw metal.
• Paint may contain several elements which need to be tested at lower levels within
metal alloys (Ti & Zn in white paint, Fe in red paint, Cr in green paint).
• Oil, grease or lubricates may contain high levels of the following elements: lithium,
aluminum, barium, strontium, molybdenum or calcium.
Plated surfaces may have high levels of the following elements: zinc, chromium, nickel, or
copper.
CAUTION Anything on the metal surface will become part of your test results!
Sample Analysis Preparation
You need to clear the surface of your samples of any paint, plating, or any oxidation such as
rust or verdigris before analysis. In order to accomplish this, you need the following:
• Isopropyl alcohol - not rubbing alcohol, which contains oils.
• Lint-free paper.
• Diamond paper - P/N 179-1202- cut into 1 inch/2.5 cm squares. Never re-use this
paper, as it may transfer contaminants to the surface of the sample from previous
cleanings. Depending on the state of the sample, several squares may be needed per
sample.
Thermo Scientific
Niton XL3 Analyzer User’s Guide
89
5
Common Operations
Metal Sample Prep
• A Sample Grinder for removing deeper surface contamination. Choice of grinding
wheel media also may be important, depending on what you are testing for. Never
re-use grinding media, as contaminants can be transferred from sample to sample on
the media itself.
For light contamination on hard metal reference standards, remove the oxidation by
scrubbing the dry sample lightly with the diamond paper square, using the fingers to maintain
pressure. If the diamond paper begins to load up with material, discard it and use a fresh
square. When the oxidation is removed, wipe the sample with lint-free paper soaked with
isopropyl alcohol to remove any oils or dust. Let the sample dry before attempting analysis.
For soft metal reference standards, wipe the sample with lint-free paper soaked with isopropyl
alcohol, then remove the oxidation by scrubbing the wet sample lightly with the diamond
paper square, using the fingers to maintain pressure. If the diamond paper begins to load up
with material, discard it and use a fresh square. When the oxidation is removed, wipe the
sample again with lint-free paper soaked with isopropyl alcohol to remove any oils or dust. Let
the sample dry before attempting analysis.
Oils, lint and dust can be removed by wiping the sample with lint-free paper soaked with
isopropyl alcohol. Let the sample dry before attempting analysis.
Surface Oxidation
With the exception of a limited number of metal types, most metal alloys form an oxide
covering on the surface when exposed to oxygen or air. This oxide covering is visible in carbon
and low alloy steel as a red colored substance called rust. Other metal alloys form oxidation
which is not always visible, but that does not mean that it is not present. If the test results for
low concentration elements are higher or lower than expected, remove the oxide coating by
grinding and retest. Follow proper safety procedures when changing discs or grinding
materials.
During a recent case study the effects of sample preparation became apparent. A customer
asked for low detection limits of nickel, chromium and copper in carbon steel pipe. The
reported chemistry of the purchased material is listed on the first line in the chart below. The
test results of a hand held Niton XL3t 900S GOLDD instrument appears in the second line
of the chart. The results from a test on the unground surface appear in the bottom line of the
chart. Note the values for nickel and copper in this carbon steel alloy in the chart below. The
oxidation on the surface of this pipe was not visibly egregious. We need to always be wary of
the presence of even low levels of oxidation and their possible effects on analytic accuracy.

Painted Surfaces
Paint is a mixture of several items that are combined into a liquid which is applied to the
surface of materials such as metal. Once applied this liquid dries with time and adheres to the
surface of metal. Paint is used to protect or decorate the metal item. Paint can also be used to
identify or mark the metal during the manufacturing process.
Components of paint are divided into classifications of pigments, binders, solvents, additives
and fillers. The inorganic elements in pigments will contribute to increases in displayed values
for those elements if paint on the metal surface is not removed prior to testing. Be especially
careful of the presence of heavy elements, which can also act to shield x-rays from lighter
elements in the metal sample.
The following is a list of some of the most common components of paint:
White Paint
• Antimony (Sb)
• Lead (Pb)
• Titanium (Ti)
• Zinc (Zn)
• Cobalt (Co)
Red Paint
• Iron (Fe)
• Lead (Pb)
• Green Paint
• Chromium (Cr)
An experiment was conducted to determine the effect and severity of surface problems on
XRF results. Results from analyses of a 1541 alloy steel sample are shown below, before and
after surface grinding. The sample had painted markings, of light to medium thickness, on
the surface, as well as light rust. Note the change in titanium, zinc and cobalt levels after
surface grinding.

Oil, Grease & Cutting Oils
Oil and grease contain a number of elements combined into a viscous substance and applied
to moving parts in order to reduce friction. Grease coatings can remain on component
surfaces after it has been removed from service. Grease can also be applied to a metal's surface
by accidental contact with other materials coated in heavy grease. Metals can also be coated in
oil as a result of cutting and machining processes in manufacturing.
Grease and oil may contain the following elements:
• Aluminum (Al)
• Zinc (Zn)
• Molybdenum (Mo)
• Sodium (Na)
• Calcium (Ca)
An experiment was performed to show how grease on metal surfaces affects XRF results. A
carbon steel sample was cleaned and ground as a control surface for the experiment. XRF tests
were performed on the control surface, and again after light and heavier layers of automotive
wheel bearing grease were applied to the surface of the steel sample. Results are shown below.
Note the elevated levels of molybdenum, cobalt and zinc from the grease.

Anodized, Plated and Galvanized Surfaces
Anodizing is the process of polarizing the metal surface into a passive state which protects it
against corrosion. This process is most often applied to aluminum alloys.
Galvanized steel is one of the most common of the coated surfaces. In this process, steel is
passed through a molten bath of a zinc alloy. Zinc reacts with the steel metal to form a
bonding layer on the steel surface. The zinc layer does not separate from the steel and forms a
protective layer that protects the steel from oxidation.
Galvanized layers are relatively thick compared to other plating elements and methods. When
grinding to remove the zinc coating, you will find increased zinc values even when you can see
the steel surface. Grind a little further and zinc values will disappear. Zinc clings to the surface
of the sanding disc, so you will need to frequently change discs.
Electroplating is another common practice of applying a coating which not only protects the
surface from oxidation, but also improves the base material's wear resistance, lubricity and
improves the overall aesthetics of the product. The electroplated coating is generally thinner
and more evenly applied than galvanizing. Electroplating has a wide range of elements and in
some situations there may be two or more different coatings on the same part.
The following is a partial list of elements that are used to plate the surface of base metals:
Ni, Cr, Cadmium (Cd), Tin (Sn), Zn, Al
Cordless Right Angle Drill
This style of drill is recommended for most surface preparation in the field because it gives the
operator the greatest amount of control, and thus safety, when grinding samples. When
moving a sanding disc on a conventional drill over a sample, forces tend to produce
movement the operator may find difficult to control. Control and stability are important in
grinding from effectiveness and safety perspectives.
A cordless right angle drill similar to the one pictured below is recommended for light to
medium surface removal. For materials with heavy oxidation such as carbon and low alloy
steel, an angle grinder, explained in the next section, is recommended. A kit with the drill,
batteries and charging units, can be purchased from ThermoFisher, or companies such as
DeWalt, Hitachi, Makita, Milwaukee or Ryobi.

Example of Right Angle Drill
A disc holder is needed with the drill to hold the sanding disc. (In the US, we recommend a
3.0 inch disc holder. It has a 0.25 inch shank to insert into the chuck of the drill.) If sanding
discs are ordered from a local supplier, attention should be paid to the method of attaching
the sanding disc to the disc holder. There are three types of connections: metal snap-on,
plastic twist and plastic snap-on.

Assembling the Grinder
Remove the battery before assembling the grinder, backup pad and sanding disc. Start by
installing the backup pad onto the drive shaft of the grinder, or, with some backup pads. You
will need to screw it onto the threaded shaft.
Next place the sanding disc over the drive shaft onto the backup pad. Hold the locking button
on the reverse side of the grinder while tightening the retaining nut into the hole of the
sanding disc.
Once the backup pad, sanding disc and locking nut are secured, reinstall the battery. The
grinder is now ready for use.
Sanding Discs
It has been well tested and determined that samples can be easily contaminated by the abrasive
material contained in and on a sanding disc. An example would be the increase in aluminum
content of carbon steel after grinding the sample with a new aluminum oxide sanding disc.
Aluminum from the aluminum oxide disc imbeds itself in the surface of the steel sample and
an XRF would show an unusually high aluminum concentration.
Thermo Scientific
Niton XL3 Analyzer User’s Guide

Common Operations
Metal Sample Prep
Aluminum oxide is the most common abrasive surface used today. For most applications it
will be safe to use aluminum oxide discs. But if test results for aluminum in any metal alloy are
significantly higher than expected, switch to another type of abrasive disc. Also, when
grinding aluminum, aluminum oxide discs tend to trap aluminum from the metal surface into
the disc surface. Once this happens, the disc looses its efficiency and cross contaminates the
next sample.
Silicon Carbide
Silicon carbide discs are a good alternative for aluminum oxide and the cost of a disc is only
slightly higher than aluminum oxide. This adhesive type is best for grinding aluminum,
copper and other soft metals.
Zirconia Alumina
Zirconia alumina discs are more expensive than aluminum oxide or silicon carbide but they
last much longer and so may be the best investment. Few metal alloys have low additive levels
of zirconium, so it is one of the safest abrasive types for general use.
One exception is the Aluminum alloy Al 7050 which is a near twin to alloy Al 7075 except for
the ~0.1% Zr in 7050. Therefore, if 7075 is ground with Zr grinding paper it may be
erroneously identified as Al 7050 due to the Zr transferred from the grinding disk to the
surface of the Al 7075. s
Diamond Sanding Paper
Do not use diamond sanding paper for surface preparation in the field. Even after extensive
and aggressive sanding with diamond paper, a metal surface will not be prepared properly.
Diamond sanding paper is only recommended for removal of very light oxide coatings on flat
surfaces such as analytical reference standards.
• Nickel, cobalt, and steel alloys should be ground using 36, 40, 50 or 60 grit discs.
The selection of a grit size of 100 or la
• inum, copper alloys, and other softer metals should be ground using 60 or 80 grit
discs.
• Grinding stones are not recommended because they will absorb surface material and
transfer them onto the next surface ground.
Safety Rules
When using a grinder, follow these safety rules:
• When changing sanding discs, always remove the grinder battery to prevent
accidental activation of the grinder.
• Allow the grinder to stop spinning before placing it on a flat surface.

Soil Sample Prep
Examine the site for differences in surface characteristics before sampling. Valid results depend
on a sufficient and appropriate selection of sites to sample. Incorrect sample collection may
give rise to misleading or meaningless results, regardless of the analysis method. Delineate
sections with different characteristics and treat them as different areas. It may be desirable to
subdivide larger areas even if they have the same characteristics to ensure a thorough
examination. Make certain to label each bag thoroughly. Common information included on
each bag includes the person and/or the company who collected the sample, the location and
area where the sample was taken, and the date the sample was collected.
Prepared sample analysis is the most accurate method for determining the concentration of
elements in a bulk medium using the instrument. Sample preparation will minimize the
effects of moisture, large particle size, variations in particle size and sample non-homogeneity.
Note More sample preparation (drying, milling and sifting) will yield greater accuracy. The
drier, finer, and more homogeneous the particles, the better the measurements.
Preparing Bulk Soil Samples
We recommends establishing a specific sample protocol. Following this protocol for preparing
and testing samples is vital for achieving a level of accuracy comparable with laboratory
results. The equipment you need to prepare samples is included in your kit. Among these are
a mortar and pestle, several different sized metal sieves, and cups to hold the samples
CAUTION All test equipment must be kept clean to prevent contaminationof samples.
Cleaning Your Equipment:
The mortar, pestle, and grinding mill may be cleaned with dry paper towels. You can also
clean the mortar, pestle, and the mill’s container with water, but be sure each is absolutely dry
before using them on another sample. The mortar and pestle may be cleaned by grinding
clean, dry sand in the mortar. Use the short bristle brushes (included in your Soil Testing Kit)
to clean the sieves. If you have an electric soil grinder in your kit, when the soil grinder blades
wear out, unbolt the worn blades and replace them. Call the Thermo Sales Department at
1-800-875-1578 for replacement blades.
Note Using the soil grinder may artificially increase the amount of Fe in soil samples.

Sample Preparation
Prior to analysis, the material should be dry and well homogenized. Ideally, the entire sample
should be dried to constant weight, sifted to remove gravel and debris, and ground or milled
to a fine powder. Dry the sample if it is moist and cohesive. The sample can be dried in any of
several ways. Choose one of the following:
• Oven dry the sample for approximately 2 hours at 150° C, until the sample reaches a
constant weight. Note: Oven drying is inappropriate when volatile compounds may
be present in the sample. For example, lead present as tetraethyl lead would be driven
off by the heat of drying. Some forms of mercury and arsenic are volatile. Air drying
will preserve more of these volatile substances.
• Air dry the sample overnight at room temperature in a shallow pan.
• Stir gently and warm the sample in a pan over a hot plate or burner.
Coning and Quartering
You may need to divide your sample at various times during preparation. Coning and
quartering is a method for dividing the sample into homogenous quarters.
• Pour the dry material slowly and carefully onto a flat sheet or pan, forming a
symmetrical cone. Divide the cone into equal piles using a flat thin-bladed tool, such
as a knife or ruler. Divide these in half again.
• Now you have four samples, each one-quarter the size of the original and each more
homogenous than the original.
• Grind the sample to break up dirt clods and/or paint chips.
WARNING Grinding and sifting dried samples produces dust. Even clean soil contains silica,
which may be hazardous when airborne. Prepare all samples in a ventilated area; wear a mask,
gloves, and an apron; and spread a drop cloth.
Sift using the #10 (2mm) mesh and separate out the larger pieces (stones, organic matter,
metallic objects, etc. Examine the larger particles by eye but do not include in the sample.
Grind the sample again so its particles will be finer and more homogenous. Use mortar and
pestle, or an electrically powered grinding mill. Sift at least 10 grams of the sample through
#60 (250 ?m) and #120 (125 ?m) mesh. Re-grind the un-passed material until the entire
fraction is able to pass. Mix the resulting sample.
Placing the Sample in an XRF Sample Cup
Note The sample container should be a sample cup of a type that can be filled from the rear;
that is, the side opposite the window (e.g. Thermo NITON Part Number 187-466). Thermo
recommends using a 1/4 mil Polypropylene film (e.g. Thermo NITON Part Number
187-461). A supply of cups and films are included.

The container used to hold the sample will affect the accuracy of the measurement. Use a
container with as thin-walled a window as is convenient and use the same kind of container
and window for each sample. Consistency and careful attention to detail are keys to accurate
measurement.
PLACE FILM
Place a circle of polypropylene film on top of an XRF sample cup. This film goes on the end
of the cup with the indented ring. Thermo recommends preparing the cup ahead of time, if
possible.
SECURE FILM
Secure the film with the collar. The flange inside the collar faces down and snaps into the
indented ring of the cup. Inspect the installed film window for continuity and smooth, taut
appearance.
FILL CUP
Set the cup on a flat surface film-window-side down. Fill it with at least five grams of the
prepared sample, making sure that no voids or uneven layers.

Liquids
Fill an XRF sample cup with the liquid to be tested (do not pad the sample with cotton). The
cup must be full so it is best if some liquid is allowed to overflow when the cap is put on.
Sludge
Sludge can be placed directly into an XRF cup for screening. This is considered in-situ testing
because no attempt has been made to prepare the sample. For more accuracy, the sludge can
be dried, sieved, and ground. Prepare in an XRF sample cup and test the same way you would
with a soil sample. For risk analysis, it is advisable to use a 60-mesh sieve to isolate and test
only fine particles.

Changing Precision (Sigma Value)
Sigma is the symbol used for Standard Deviation, a measure of how much a set of numbers
deviates from the mean. For example, each of the three data sets {0, 0, 14, and 14}, {0, 6, 8,
and 14} and {6, 6, 8, 8} has a mean of 7. Their standard deviations are 7, 5, and 1,
respectively. The third set has a much smaller standard deviation than the other two because
its values are all close to 7. In a loose sense, the standard deviation tells us how far from the
mean the data points tend to be. The number of standard deviations between the process
mean and the nearest specification limit is given in sigmas. As process standard deviation goes
up, or the mean of the process moves away from the center of the tolerance, the sigma number
goes down, because fewer standard deviations will then fit between the mean and the nearest
specification limit.
Confidence Intervals
Confidence intervals assume that the data are from an approximately normally distributed
population - generally, sums of many independent, identically distributed random variables
tend towards the normal distribution as a limit. Using this assumption, about 68 % of the
values must be within 1 standard deviation of the mean, about 95 % of the values must be
within two standard deviations, about 99.7 % must lie within 3 standard deviations, and
about 99.99% of the values must lie within 4 standard deviations.
The greater the sigma value of the test, the more confident you can be that the sample is as it
appears, but the more difficult and time consuming the testing must be to verify this. That's
why it's important to use the most appropriate sigma value for the test. By adjusting the sigma
value for each type of test, you can optimize the process for your needs.

Viewing the Spectrum
SpectraView
SpectraView enables you to to visually inspect the fluorescent x-ray peaks obtained from any
sample and qualitatively identify them using the on-board software. In SpectraView Mode,
the spectrum is displayed using a linear energy scale along the x-axis, with the count rate
autoscaled logarithmically on the y-axis so that the highest peak on the screen reaches the top
of the scale.
How to Use SpectraView
You can access the SpectraView screen after taking a measurement in any mode, or while
viewing a previous measurement, by selecting Spectra from the NAV Menu. Once you are in
SpectraView, you can use the up and down positions of the 4-way touch pad to scroll through
the spectrum, or you can tap on the spectrum display with the stylus to place the cursor at the
point you tapped. The vertical cursor line indicates the current position along the spectrum.
Viewing the Information in SpectraView Mode
Figure 27. The SpectraView Screen
By default, the following information is shown along with the spectrum:
• The Reading number (Bottom Left) in the form "Read:x", where x is the Reading
number.
• The position of the cursor on the energy scale (Bottom Left, under the Reading
number), in the form "E: x.xx KeV", where KeV is kilo electron volts.
• The count rate (Bottom Left, under the energy position), in the form “R:x.xx”.

• Ka, Kb, La, Lb, and/or Lg peaks of the three elements closest to where your cursor is
positioned on the energy scale (Bottom Right). This information is written with the
element symbol first, followed by either Ka (K shell alpha peak), Kb (K shell beta
peak), La (L shell alpha peak), La (L shell beta peak), or Lg (L shell gamma peak). An
example would be "Al Ka 1.48." To determine if a given element is present, look at
the count rate at that cursor position.
Note SpectraView cannot be used to determine exact element percentages in a sample.
Fitting the Spectrum
By using the touch screen, you can select parts of the displayed spectrum and zoom in. Touch
and hold the stylus to the screen immediately before the area of the spectrum you wish to
enhance, then - still holding the stylus to the screen - sweep it across the area of the spectrum
you wish to see closer, lifting the stylus from the screen when you pass the end of the area of
interest. The screen will display vertical lines to either side of the area of interest, delineating
the boundaries of the area.

spectrum to view.
The Spectra1 choice will display the spectrum produced by the first Range.

Thickness Correction
Plastics, and polymers in general, unlike metals or soil, are very weak absorbers of X rays. This
is because polymers are composed mainly of very light elements such as carbon and hydrogen.
While just half a millimeter of steel will completely stop 23.1 keV energy X rays of cadmium,
for example, it takes at least 10mm of plasticized PVC and as much as 100mm of
polyethylene (PE) to do so. Fortunately, polymers that may contain cadmium (Cd), lead (Pb)
and other restricted elements would also contain considerable quantity of elements such as
antimony (Sb), bromine (Br), titanium (Ti), etc. Their presence results in much stronger
absorption of X rays which means that, instead of 100mm, it takes only about 15mm of
compounded PE to achieve saturation thickness for these X rays. If the thickness of analyzed
polymer sample is less than 5mm for PVC or less than about 9mm for a “typical” PE, the
measured intensity of X rays will be a function of both analyte concentration and sample
thickness. This is why measurements performed on thin samples (less than saturation
thickness) need to be corrected for thickness.
How to apply Thickness Correction.
In order for the instrument to apply thickness correction to the measured concentration
results, the user must be using the Thickness Correction screen and enter the thickness of the
analyzed plastic object expressed in [mm] before the measurement is initiated. The thickness
may be entered with precision to the second decimal place, although in practice only one
decimal place is sufficient for effective correction.

When to use Thickness Correction
Thickness Correction should only be used during the analysis of plastic (polymer) objects. It
has been experimentally verified that the correction algorithm will yield satisfactory results,
for a 60 second minimum testing time, for samples as thin as 0.3mm. Nevertheless, the
recommended range of use of the correction is from 1mm upwards. It is imperative that this
correction is not used for thin films such as single foils and plastic membranes; analysis of thin
films is performed using the Thin Sample Mode. (Contact Contact Thermo Scientific or your
local Niton Analyzers representative for information on this testing mode.)
Whenever possible, one should analyze as thick a sample as available. For example, if the
analyzed object is a piece of heatshrink tubing with wall thickness of 0.3mm, the best way to
analyze it is to obtain several pieces of the tubing (four for example) and stack them like a flat
sandwich, with the thickness correction set to 1.2mm. Doing so makes for faster and more
precise analyses. While it would be possible to analyze just a single layer of the tubing with
correction at 0.3 mm, by stacking several layers we reduce the relative error of measurement
(by a factor approximately equal to the square root of the number of layers). Conversely, when
analyzing thinner samples, we need to extend the measurement time fourfold (by the number
of layers) in order to maintain the same relative error of measurement. We can see how
quickly measurement time would escalate to impractical levels for thinner samples.
Examples: The most frequent instances in which thickness correction would be called for are
analyses of plastic sheeting or plastic insulation on wires and/or cables and heat shrink tubing.
Flat plastic sheeting or plastic enclosures pose no problems. We can either analyze an object
“as is”, or stack several layers of it before analysis. Plastic insulation such as that on wiring or
cables requires a little more sophisticated approach. First, the wire must be removed so that
only insulation is analyzed. Then, the insulation should be flattened for analysis, and a
thickness correction should be applied that is equal to double the wall thickness. Alternatively,
if the insulation is stiff, it should be cut lengthwise into strands which are placed on the
indtrument for analysis. The applied thickness correction should be equal to the wall
thickness of the sleeve. Both operations are shown in Figure 37 and Figure 38.

PVC Wire Insulation With Conductor Removed
A piece of large diameter heat shrink tubing presents an interesting case. It is tempting to
analyze this object as is - see Figure 39. However, one needs to know that while lead or
bromine or chromium X-rays from the upper wall of tubing will not contribute to the signal
measured, X rays of such elements as cadmium, antimony, tin or barium in the upper wall will
significantly contribute to overall signal. It is therefore imperative to either flatten the tubing
for analysis or cut it in pieces and then analyze as shown in Figure 40.

The Safety Settings Screen enables you to change the Method of Operation for your
analyzer. Each checkbox on the screen enables or disables the safety device named for purposes
of the preconditions for operation. For example, checking the Proximity Button Required
checkbox sets the engagement of the Proximity Sensor as a precondition for operation.
Checking the Proximity Button Required checkbox and the Interlock Button Required
checkbox sets the engagement of both the Proximity Button and the Interlock Button as
preconditions for operation.
Safety settings always override start-stop settings. If your safety setting requires the use of the
Proximity Button, you cannot set start-stop settings which ignore the Proximity Button. For
example, the Easy Trigger start-stop setting must have the Backscatter safety setting enabled.
While using Easy Trigger, you cannot disable Backscatter.
WARNING The backscatter sensor is enabled by default and acts as a recommended safety
feature for most applications. Some sample types, however, cannot be analyzed when this
feature is enabled. Samples that present very little mass to the analysis window, such as certain
thin films, thin layers of plastic, and very thin wires, may not be of sufficient mass to allow the
analysis to continue while backscatter is enabled. One should disable the backscatter feature
only when necessary to analyze such low mass samples, and re-enable the feature when
finished with these sample types. These samples also provide very little absorption of the
primary x-ray beam so it is typically most appropriate to analyze these samples in a test stand
when possible.

Methods of Operation
CAUTION After being powered on, your Niton Analyzer will perform an internal
re-calibration before an analysis is initiated. It is recommended that you let your analyzer
warm up for ten minutes after start up, before testing is begun.
There are six different methods of operation for taking a sample measurement, and your
analyzer will be configured to use one of those methods for alloy samples, depending on the
regulatory requirements of your locality. These methods are:
• Trigger-Only method. With the Trigger-Only method, you only need to place the
measurement window flush with the sample to be analyzed and pull the trigger for sample
analysis to be initiated.
• Trigger-and-Proximity-Sensor method. With the Trigger-and-Proximity-Sensor method,
you must place the measurement window against the sample to be analyzed to engage the
proximity sensor on the front of the analyzer, then pull the trigger for sample analysis to
be initiated.
• Momentary-Trigger-Touch-and-Proximity-Sensor method. With the
Momentary-Trigger-Touch-and-Proximity-Sensor method, you must place the
measurement window against the surface to be analyzed to engage the proximity sensor
on the front of the analyzer, then pull the trigger. The trigger may be released and the
reading will continue until you release the proximity button, or other criteria (such as
Max Time) are reached.
• Trigger-and-Interlock method. With the Trigger-and-Interlock method, you need to
place the measurement window close to the sample to be analyzed, press and keep
pressing the interlock button at the rear of the analyzer with your free hand, then pull the
trigger for sample analysis to be initiated.
• Trigger-Interlock-and-Proximity-Sensor method. With the
Trigger-Interlock-and-Proximity-Sensor method, you must place the measurement
window against the sample to be analyzed to engage the proximity sensor on the front of
the analyzer, press and keep pressing the interlock button at the rear of the analyzer with
your free hand, then pull the trigger for sample analysis to be initiated.
• Easy Trigger method. With the Easy trigger method, you need only place the
measurement window against the sample area and pull the trigger once to initiate a
sample analysis. Your analyzer will continuously sample the backscatter, using a complex
internal algorithm, to determine if the measurement window is against a sample or
pointing to the empty air. If it finds that there is no sample directly against the
measurement window, the analyzer will stop directing radiation through the window as
soon as this determination is made.
The analyzer is constantly checking the backscatter characteristics to determine if a sample is
against the measurement window, whether or not the Easy Trigger method is being used, and
will shut off any radiation directed through the window if it determines that there is no
sample present.

Niton XL3 Analyzer User’s Guide
Thermo Scientific

Advanced Settings
Safety Settings
With any of these methods, analysis will stop if any one of the preconditions are violated. For
example, with the Trigger-Interlock-and-Proximity-Sensor method, if the trigger or the
Proximity Sensor or the Interlock is released, the reading will stop immediately, and the X-ray
tube will shut down.
After your analyzer is calibrated, initiate a sample reading using the appropriate method. If
you attempt to initiate a sample reading using a different method, the analyzer will inform
you that one or more of the preconditions need to be met in order for sample analysis to
begin.
Note The LED lights will blink whenever the x-ray tube is on.
WARNING The nose should not be touched during sample testing and calibration. If an ESD
event occurs during measurement, the instrument may terminate the testing in progress and
automatically reset to LogOn screen. Any test data collected prior to reset will be lost and the
testing may have to be repeated.
WARNING The preconditions for operation must be continued for the duration of the
reading. If the preconditions are violated, the x-ray tube will turn off, the calibration shutter
will close, and the measurement will end. The LED lights will stop blinking when the
measurement is ended. The flashing of the LED lights is not synchronized to minimize
power consumption.
To end the test, simply release the trigger mechanism, or any other applicable preconditions.

He-Purged Analysis
Helium purge is required for optimum detection of light elements such as Mg, Al, Si and P.
For analyses using helium, we recommend using the default Range setup, as shown below in
Figures 5 and 6. As with other energy dispersive XRF analyzers, the longer the testing time,
the better the statistical precision of the reading. See Adjusting the Element Range for more
on setting Ranges.

The user can see the precision improving with analysis time by watching the third column on
the analysis display – the 2-sigma error. This value decreases as reading time increases.
Knowledge of this relationship is important, especially for light element work.
See Metals Analysis and/or Mining Analysis for more information on sample analysis. See also
Avg Forward, Spectrum:On/Spectrum:Off, Enable LEC/Disable LEC, and Set Pass/Fail for
more information on specific aspects and methods of analysis.

Alloy Grade Libraries
Using a library of alloy grade specifications, your alloy analyzer will attempt to identify an
alloy sample being analyzed. It does this by comparing the chemistry analysis results against
the minimum and maximum specifications in the library. The library is an .alb or .clb file,
and is viewable, editable, and upload-able via the included NDT program. Your analyzer can
store two alloy grade libraries in its memory, and automatically chooses one of the two for use
while testing. See Managing Libraries for information on how to manage your Libraries.
Selecting the He Library
The 900 library will be auto loaded when the Light Range is selected. When the Light Range
is de-selected, the standard 800 library will autoload. Selecting Switch Library (Main) from
the Tools Menu will not work. It is disabled in favor of the autoloading. Alternately, you can
select Toggle Helium from the Tools Menu. In non-GOLDD analyzers, this will select the
Light Range and change to the 900 Library. Selecting it again will de-select the Light Range
and change to the 800 Library.

completely purged from the system.
Note When switching between Helium and Non-Helium applications on a GOLDD
analyzer, allow the helium to dissipate out of system for at least ten minutes before beginning
non-helium analysis. To expedite this process, you may remove the Measurement Window

set forth in the product documentation, published specifications or
package inserts. If a period of time is not specified in Seller’s product
documentation, published specifications or package inserts, the warranty
period shall be one (1) year (unless otherwise agreed upon at time of
purchase) from the date of shipment to Buyer in the country of
purchase. Any part replaced on an instrument, covered by the original
factory warranty, will be warranted for the remainder of the instrument's
factory warranty. Seller agrees during the Warranty Period, to repair or
replace, at Seller's option, defective Products so as to cause the same to
operate in substantial conformance with said published specifications;
provided that Buyer shall (a) promptly notify Seller in writing upon the
discovery of any defect, which notice shall include the product model
and serial number (if applicable) and details of the warranty claim; and
(b) after Seller’s review, Seller will provide Buyer with service data and/or
a Return Material Authorization (“RMA”), which may include
biohazard or other Radiation safety decontamination procedures and
other product-specific handling instructions, then, if applicable, Buyer
may return the defective Products to Seller with all costs prepaid by
Buyer. Replacement parts may be new or refurbished, at the election of
Seller, the warranty of these parts expire with the instrument warranty.
All replaced parts shall become the property of Seller. Shipment to
Buyer of repaired or replacement Products shall be made in accordance
with the Delivery provisions of the Seller’s Terms and Conditions of
Sale. Accessories and Consumables are expressly excluded from this
warranty (see list A for details).
Notwithstanding the foregoing, Products supplied by Seller that are
obtained by Seller from an original manufacturer or third party supplier
are not warranted by Seller, but Seller agrees to assign to Buyer any
warranty rights in such Product that Seller may have from the original
manufacturer or third party supplier, to the extent such assignment is
allowed by such original manufacturer or third party supplier.
