1.2 Anatel® PAT700 analyzer overview
The Anatel® PAT700 analyzer provides TOC analysis for pure and ultra-pure water
processing.
The PAT700 oxidizes a water sample to determine the TOC in the sample. The analyzer traps
a sample in the analysis cell, exposes the sample to ultraviolet (UV) light, and monitors
changes in temperature and conductivity until the sample has completely oxidized. Once full
oxidation has occurred, the analyzer reports TOC, temperature, conductivity, and the
oxidation curve. The PAT700 incorporates the OASIS™ onboard, automated standards
introduction system that simplifies analyzer performance testing using standards bottles
tagged with RFID technology.
A touch-screen interface provides access to all analyzer functions. The user interface consists
of a home screen from which all user operation initiates. The home screen displays the
current status of the analyzer, TOC level, and environmental data. The software can display
data in a number of user-selected formats, including TOC, compensated and uncompensated
conductivity, and temperature in engineering units, with graphical representations of the data.
Compliance with 21 CFR Part 11 is ensured with password protection and an audit trail of all
user intervention.

1.3 RFID technology
The Aantel PAT700 on-line TOC analyzer Onboard Automated Standards Introduction
System (OASIS™) employs Radio Frequency Identification (RFID) technology, a registered
radio frequency device. The RFID system in the PAT700 operates over a very short distance
to eliminate any interference with other wireless communications.
The term RFID describes a system that transmits data wirelessly, using radio waves, over a
very short distance. An RFID system is comprised of a “tag” and a “reader/writer”. In the
PAT700 analyzer, the tag is attached to the standards bottles used in calibrations
(conductivity and TOC), validations, and system suitability tests. The RFID tag consists of a
microchip attached to a radio antenna mounted on a substrate. The RFID tag is attached to
the bottom of the standards bottle. The microchip contains data about the standard contained
in the bottle. The PAT700 OASIS system contains four RFID reader/writers permanently
mounted inside the analyzer that align with the bottle RFID tags when the bottles are fully
loaded in the analyzer. The reader/writer retrieves the data stored on the RFID tags located
on the bottom of the standards bottles. The RFID reader/writers have antennas that emit radio
waves and receive signals back from the tags on the standards bottles. The information
provided from the tag includes the identity of the standard, the standard’s concentration, date
of expiration and other pertinent data.
WGM - 26 July 2007 - Edition 01-d4
PAT700 Total Organic Carbon Analyzer – Before You Begin Page 3
Anatel Operator Manual
The reader/writer takes the data received from the tag and passes the information in digital
form to the PAT700 processor. The RFID system in the PAT700 can read and write to the
RFID tags attached to the standards bottle. The writing feature allows the PAT700 to write
data to the bottles showing that the bottle has been used and provides for writing of data for
the exclusive excursion sampling feature.
The RFID system in the PAT700 does not require any user intervention to operate. The
system operates automatically when bottle tests are performed. The system automatically
turns on and off to read and write data only when necessary. When enabled, the radio
frequency modulation emitted from the antennas is fixed at 13.56 Mhz. There are no user
serviceable parts associated with the RFID system. The RFID reader/writer board assembly
should only be serviced by a Hach Ultra certified service representative.
Since the RFID labels on the standards bottles contain the data necessary for each standard,
the labels must not be removed from the bottle. Without the label, the RFID reader/writer has
no data to read and will not operate as intended.

1.8 Definitions of terms
The following terms are used throughout this manual:
Conductivity. A measure of the ability to conduct current through water. Conductivity, very
low with high-purity deionized water, is the reciprocal of resistivity and is measured in
microsiemens per centimeter (μS/cm).
Megohm (M). A measurement of 1,000,000 ohms.
Microsiemens (μS). A unit of conductance in the metric system equivalent to one millionth of
an ampere per volt (1 µS = 1 x 10-6 A/V).
Normalize. To make conform to a standard. In this case, the user performs calculations on
the raw data to produce a result in a standard unit of measure.
Organic. Organic chemicals, including carbon atoms in complex molecules, but not including
carbonate (CO2, HCO3, CO3) or cyanide (CN) related compounds. Oxygen is very common
in organics, and they almost always include hydrogen.
Oxidation. The loss of electrons by a chemical species, typically with oxygen. Organic
carbon, for example, oxidizes to carbon dioxide and water.
Parts per billion (ppb). A term used to report trace chemical analyses. It refers to the
concentration of the element or compound present within one billion parts of water. One
microgram per liter (µg/L) is equal to 1 ppb).
Resistivity. Resistance, measured in megohmcentimeters (M-cm), to the flow of electrical
current through high-purity water. Resistivity is a means of continuously measuring the
purity of the water and is the reciprocal of conductivity.
Temperature compensation. Conductivity and resistivity measurements normalized to
25 °C (77 °F) for reporting purposes. Normalized conductivity and resistivity
measurements reflect the values that would be reported at a sample temperature of 25 °C
(77 °F) using a model based on sodium chloride in water. Conductivity and resistivity of
electric current in water depend on the temperature of the water. The lower the
temperature, the lower the conductivity and the higher the resistivity.

Operator Manual Anatel
WGM - 26 July 2007 - Edition 01-d4
Total organic carbon (TOC). A measurement of the organics present in water based on its
carbon content. High-purity water measures TOC in parts per billion (ppb). Total organic
carbon is used interchangeably with total oxidizable carbon.

Mounting general considerations
Follow these guidelines when installing the analyzer:
• Locate the analyzer where it is accessible for operation, service and calibration.
• Minimize the distance between the water system sample point and the analyzer to
allow for representative sampling.
• Locate the analyzer where the ambient temperature remains between 15 and 35 °C
(59 and 95 °F).
• The transmitter mounting bracket is installed independently from the analyzer. Once
mounted, the analyzer hooks on the mounting bracket and locks into place with twist
latches.
• Mount the transmitter mounting bracket to a stable, flat surface or dual instrument
poles.
• The front of the analyzer requires 12 inches (30.48 cm) of clearance to allow the doors
to open completely.
• The analyzer is available with ¾-inch conduit openings or quick-connect fittings for
power and I/O wiring. If conduit is used, install fittings that ensure a complete seal with
the openings and are properly sealed to keep the analyzer electronics compartment
watertight.
Mounting to a wall
Follow these guidelines and refer to Figure 2-1 and Figure 2-3 to mount the transmitter to a
wall or other flat, rigid surface:
• Use 5/16-inch (8 mm) diameter screws or bolts and nuts to mount the analyzer to a
wall or other flat, rigid surface. Use hardware that can withstand the process
environment. Hach Ultra does not supply hardware.
• To minimize stress on the analyzer mounting bracket, secure all mounting bolts to the
same structure, which should be flat and should not vibrate or move excessively. Do
not secure bolts to separate girders, beams, or wall studs, which can move
independently.

• A female RS-232 serial port for data acquisition and control via a host computer.
• A male RS-232 serial port for connection to an external printer (1200 baud, 8 data bits,
1 stop bit, no parity).
• A USB port for data transfer via a FAT drive.
• An Ethernet® 10/100 base-T interface port for communication via Modbus® protocol.
For information about using Modbus protocol, see the instruction manual entitled Using
Modbus Protocol with the Anatel PAT700 TOC Analyzer.
• All serial ports are internally wired. Table 2-11 lists specifications for serial
communication.
Serial interface commands consist of mode set, parameter set, data read, data logger and
data history functions. The commands consist of 2-character ASCII text mnemonics. Some
commands also require one or more arguments, each delimited by at least one space (ASCII
32; 20 Hex), followed by the command mnemonic. Each command string is terminated with a
carriage return (ASCII 13; 0D Hex).
The analyzer responds to uppercase or lowercase commands.
The analyzer responds with an OK> prompt after the command has been accepted. In
addition, Data read and parameter set commands elicit a reply that consists of one or more
numeric or text values, each delimited by at least one space, and terminated by a carriage
return, line feed pair (ASCII 13,10; 0D,0Ahex).
Both commands and replies use a free field format, so the number of delimiting spaces and
length of each argument or data field may vary. If a command is rejected due to invalid syntax,
for instance, refusal is indicated by a question mark (ASCII63; 3Fhex) reply preceding the
“OK>” prompt.
The notations used to represent command arguments below are as follows:
hh:mm:ss hours:minutes:seconds
n decimal number (such as “1.234”)
i integer (such as “1”)
s text string (such as “SENSOR_NAME”)
b binary flag (“1” or “0”)

Data read commands
The data read functions return multiple values, the string terminated with a <cr><lf>.
If the analyzer is in an operational mode that does not generate a TOC result (modes 6
through 12), the TOC, TOC alarm percentage, TOC trend, profile (curve) type, and oxidation
time are not returned.
Data normally are returned only in response to issuance of the RD or RE commands. When
collecting data with a serial communications program such as Windows 95 Hyperterminal,
however, it is more convenient to have the data displayed automatically. This can be done
using the SA command, which then displays data whenever they are reported.

Chapter 3 Startup
3.1 Startup sequence
The analyzer goes through the following sequence on power up:
1) Splash window: The splash window appears at startup while the system checks
for the FAT driver, copies files, and launches the application.
2) Verify lamp monitor: After the system has initialized, it verifies that the lamp
monitor works by turning on the main lamp and ensuring a voltage is returned. The
analyzer needs to enable the lamp to warm up for a few seconds to ensure a valid
result.
3) Sample bottle check: The system checks to see if the bottles loaded in the sample
cartridge match the last known configuration. If the bottles contain RFID tags, the
analyzer reads the tags and compare them against the information stored in the
settings. If the RFID tag doesn’t match what’s stored in the settings, the settings is
updated with the new information and a warning is generated. If the settings list a
non-RFID tagged bottle in one of the bottle positions and an RFID tag cannot be
detected in that position, the analyzer assumes the bottle is still present.
4) Start sampling: If the analyzer is configured to one of the Auto TOC modes, it
starts sampling after it has powered up.
5) Print header: After the system has started up, it prints a header that tells when the
system was rebooted, and its condition. It prints the column header for the normal
operation mode.

PAT700 Total Organic Carbon Analyzer – Run modes Page 33
Anatel Operator Manual
Chapter 4 Run modes
4.1 The analysis cycle
An analysis cycle is comprised of a flush of the analysis cell, oxidation, and idle time (if the
cycle time is greater than the combined flush and oxidation time).
Oxidation time varies based on the amount of total organic carbon in the sample. Flush time
is fixed and idle time varies to allow for varying analysis cycle time. See Figure 4-1.
Idle time occurs only after an online TOC analysis has been completed and only if the elapsed
time has not exceeded the value for cycle time.
• If conductivity was selected during idle, the analyzer reports conductivity during the idle
time.
• If no conductivity was selected, the analyzer verifies the lamp is off and opens the
bypass valve.

Page 34 Run modes – PAT700 Total Organic Carbon Analyzer
Operator Manual Anatel
WGM - 26 July 2007 - Edition 01-d4
CAUTION
Using the sample pump on a pressurized system could damage the pump.
Do not use the pump on a pressurized system.
In online TOC mode, the cell valve opens to flush the cell.
• If you are sampling from a zero pressure system, you need to enable the pump option
to draw water into the cell. In this case, the pump valve must be opened and the pump
started for every action that requires drawing water through the cell. The analyzer
continues to flush until the elapsed time is equal to the time value that has been set in
the setup dialog box. The cell valve is then closed to capture the sample.
• The analysis is started and conductivity and temperature readings are fed into the TOC
algorithm. Conductivity is monitored until oxidation is complete.
• When oxidation is complete, the analyzer reports the results to the home screen and
the printer if connected. It then checks to see if the elapsed time is greater than or
equal to the value for cycle time in settings. If it is, the next online TOC analysis is
started. Otherwise, it enters the idle mode.
4.2 Conductivity mode
Figure 4-2 Conductivity mode
In conductivity mode, the analyzer starts by verifying the lamp is off and the cell valve is open
to flush the cell. The analyzer reports the current readings for conductivity and temperature to
the main display every time a new value is available. The reported value is an average of the
data for over the last two seconds. The average reading will also be sent to the printer, based
on the printout settings, and the data log.
Standby
In standby, the analyzer verifies the lamp is off and all the valves are open. Standby mode
must be terminated by switching to another mode.
WGM - 26 July 2007 - Edition 01-d4

Offline
In offline mode, the analyzer verifies the lamp is off and the valves are closed.
4.3 Clean
Figure 4-3 Clean mode
In clean mode, the analyzer starts by setting the elapsed time to 0, opening the cell valve to
flush the cell, and turning the lamp on. If timed operation was selected for this mode, the
analyzer will display a countdown timer on the dialog box. Otherwise, the elapsed time is
displayed. A stop icon will also be displayed on this dialog box to enable you to terminate the
operation. The analyzer will remain in this state until the countdown timer reaches 0, you

Chapter 6 Bottle mode
6.1 Introduction to bottle mode
The PAT700 Onboard Automated Standards Introduction System (OASIS™) is used for
performing standards tests, grab sampling, and excursion sampling. Through the bottle mode,
various bottle test functions can be selected. The OASIS is automated through the use of
RFID technology (see RFID technology, page 2). When standards bottles with RFID tags are
installed in the system, the analyzer uses RFID technology to read and transmit data about
the standards to the analyzer. This system eliminates the need for manual data entry.
Although equipped to perform automatically using RFID tagged standards, you may also use
bottles without RFID tags by manually entering the standards data when prompted by the
analyzer.
Four functions are available under bottle mode: run standards, grab sample, excursion mode,
and unload bottles.
6.2 Bottle mode dialog box
The bottle mode dialog box enables you to perform actions using the bottles in the sample
cartridge. You may run calibrations, validations, or system suitability tests, analyze samples
from a bottle, install an excursion bottle to capture a sample when a TOC measurement
exceeds an alarm limit, or schedule tests to be run. See Figure 6-1.

Entry. Upon entering this dialog box, the analyzer begins running the test.
Test details. The analyzer will first turn off the pump and lamp and close all the valves. It will
then check the cell temperature. The cell temperature must less than or equal to 30 °C for the
test to continue. The analyzer will check the cell temperature once per minute. During the cool
down period, the test status label will indicate the cell is cooling down.
• After the cool down period, the analyzer will open the pump valve and the bottle 1
valve. The pump is turned on and pull XX mL plus the bottle flush volume. The pump
will then be turned off and the both valves are closed. The volume information is
updated on the RFID tag (if appropriate) and the bottle is marked as used. A standard
TOC analysis is run on the sample.
• After the analysis is complete, the analyzer will repeat the process on the same bottle
for the number of times specified in the repetitions parameter. For subsequent reps on
the same bottle, the analyzer will only pull XX mL. After all the repetitions are
complete, the analyzer will repeat the process for the rest of the bottles.
• Once all the bottles have been analyzed, the analyzer will compare the current results
to the factory calibration. If the change in slope is greater than +/-15%, the results are
automatically rejected. The analyzer will automatically move to the test summary
dialog box.
Test status label displays the current status of the test.
Test results list box lists the results of each repetition and bottle as it is running.
Cancel icon displays a message asking you to confirm your choice. If they decide to return to

Conductivity meter test
The conductivity meter test dialog box prompts you to install a verification resistor to validate
the meter’s accuracy. If the calibration is being performed on a schedule, the dialog box will
not be displayed and all operation will occur automatically. By default, the next icon is disabled
until the analyzer passes the conductivity meter test. The start test icon will also be disabled
until the verification resistor is detected. See Figure 6-13.
Figure 6-13 Conductivity meter test dialog box
Instructions label instructs you to install the resistor and touch the start test icon.
Start test icon reads the value of the resistor. The analyzer must latch the measurement
circuit relays to read the verification resistor. Once the analyzer has read the resistor value,
the relays must be unlatched to prevent damage to the circuit. The analyzer then converts this
value to conductivity by taking the inverse of the resistance and multiplying it by the cell
constant. This value is then compared to the expected value, assuming a 61.9 Kohm resistor.
If the measured value is less than or equal to ±0.1 µS/cm of the expected value, the test
passes and the next icon is enabled. Otherwise, you are notified and must cancel the
calibration.

Test details. The analyzer will first turn off the pump and lamp and close all the valves. It will
then check the cell temperature. The cell temperature must less than or equal to 30 °C for the
test to continue. The analyzer will check the cell temperature once per minute. During the cool
down period, the test status label will indicate the cell is cooling down.
• After the cool down period, the analyzer will open the pump valve and the bottle 2
valve. The pump is turned on and pull XX mL plus the bottle flush volume. The pump
will then be turned off and the both valves are closed. The volume information is
updated on the RFID tag (if appropriate) and the bottle is marked as used. A standard
TOC analysis is run on the sample.

alarm type, and a brief alarm description in chronological order, from earliest to most recent.
Upon entering this dialog box, the list scrolls to display the most recent alarm. Any new alarms
that occur while this dialog box is displayed cause the list to update.
Silence alarms icon silences the audible alarm. The next time an alarm condition occurs, the
audible alarm activates again.
Acknowledge alarms icon acknowledges all alarms in the list and clears the list. The
currently signed on user is logged to the audit trail as the user who acknowledged the alarms.
If no user is logged on, the sign on dialog box will appear. Successfully entering a user name
and password will not sign you on to the system. This information will only be used for the
audit trail entry.
Return icon returns you to the home screen.
Alarm indication
The analyzer has two operational modes: on-line and bottle. On-line TOC and conductivity are
the two primary on-line modes (although you can also select standby, off-line, manual, or
clean). In on-line TOC and conductivity modes, the main display window provides an on-
screen animation indicating the general state of water flow through the analyzer. In on-line
TOC, conductivity, or manual TOC modes, the animation area also serves as an error
condition indicator. If an error occurs in an on-line mode, the following sequence of events
occurs:
Page 106 Troubleshooting and Service – PAT700 Total Organic Carbon Analyzer
Operator Manual Anatel
WGM - 26 July 2007 - Edition 01-d4
• At each occurrence of an error, the animation area flashes red and the PAT700 makes
a sound (if a sound is programmed).
• If a process variable such as TOC or conductivity caused the error, the displayed value
of the process variable turns red.
• The animation area continues to flash red until a user acknowledges the alarm by
entering the alarm log window and pressing the acknowledge icon (bell with green
check mark).
• If the error alarm has been acknowledged and the user returns to the main display
screen, the animation area will remain solid red until the analyzer completes a full cycle
without any errors.
• Once a full cycle has occurred without any errors, the normal animation reappears and
any red process variables return to black.
• If on the next cycle the same or a new error occurs, the animation area again flashes
red and must be acknowledged by the user.
• As long as errors exist in the error log, a user can access the log and view the list of
errors.
• At any time, a user can delete the entire error log by pressing the alarm delete icon
(bell with red X). Once all errors are deleted from the error log, the alarm log access
icon on the main menu dims and the alarm log is inacccessible until a new error
occurs.
• All errors are sent to the data log.
• All alarm acknowledgements and error screen deletions are logged to the audit trail.

fatal error will appear as a full-screen, flashing message. All operation will cease until the error
condition has been corrected. The current sample is aborted. Touch the display to clear the
error message. See Table 10-1.
Warning alarms
A warning occurs any time one of the subsystems is not operating at a normal level. When a
warning condition is present, a warning indicator will appear on the display. Operation may
continue with a warning condition present. When the warning condition has been corrected,
the indicator will disappear. See Table 10-2.

Measurement alarms
A measurement alarm condition occurs any time a data value exceeds a user-defined or
system defined alarm limit. When an alarm condition occurs, the corresponding data value will
turn RED. If the value drops below the alarm limit, the value will return to its normal color.
Audible alarms
When any of the above three error types occurs, an audible alarm will sound. The audible
alarm will repeat until the alarm condition has cleared or the user silences it. Each type of
alarm (Stop, Warning, Alarm) will have its own sound. If multiple alarms are present, only the
highest-level alarm will sound.
