GC/MS represents a combination of two powerful analytical techniques: GC, which acts as a

separation technique, and MS, which acts as a detection technique. Complex mixtures of

individual compounds can be injected into the GC, either manually or by an autosampler and

then separated for presentation to the MS. The MS will generate a mass spectrum of the GC

eluate and its components. The mass spectrum can then be used for qualitative identification

as well as accurate and precise quantification of the individual compounds present in the

sample.

A triple-quadrupole GC/MS/MS system provides the extra selectivity required for trace

analysis of compounds in complex matrices.

Preface

Hydrogen Safety Precautions

xiv TSQ Series AutoSRM User Guide Thermo Scientific

Hydrogen Safety Precautions

Hydrogen is a colorless, odorless, highly flammable gas with the molecular formula H2 and an

atomic weight of 1.00794, making it the lightest element. Hydrogen gas presents a hazard as

it is combustible over a wide range of concentrations: at ambient temperature and pressure,

this ranges from about 4% to 74.2% by volume.

Hydrogen has a flash point of - 423 °F (- 253 °C) and an auto-ignition temperature of

1,040 °F (560 °C). It has a very low ignition energy and the highest burning velocity of any

gas. If hydrogen is allowed to expand rapidly from high pressure, it can self-ignite. Hydrogen

burns with a flame that can be invisible in bright light.

Before you begin using hydrogen, you should conduct a risk assessment based on the quantity

of hydrogen to be used and the conditions of your laboratory. You should ask yourself:

“What hydrogen hazards associated with this project are most likely to occur?”

“What hydrogen hazards associated with this project have the potential to result in the

worst consequences?”

• Try to reduce or eliminate the higher risks by using the proper ventilation to remove

hydrogen gas before an ignitable concentration can accumulate. You should also consider

purging the hydrogen to further reduce hazards and ensure anyone who will be working

with hydrogen has basic hydrogen safety training.

TOXIC SUBSTANCES HAZARD: Indicates that exposure to a toxic substance

could occur and that exposure could or might cause personal injury or death.

For the prevention of personal injury, this general warning symbol precedes

the WARNING safety alert word and meets the ISO 3864-2 standard. In the

vocabulary of ANSI Z535 signs, this symbol indicates a possible personal

injury hazard exists if the instrument is improperly used or if unsafe actions

occur. This symbol and another appropriate safety symbol alerts you to an

imminent or potential hazard that could cause personal injury.

Symbol Descriptor

WARNING FIRE HAZARD: The use of hydrogen as a carrier gas is dangerous. Hydrogen is

potentially explosive and must be used with extreme care. Any use of hydrogen gas must

be reviewed by appropriate health and safety staff and all installations of hydrogen systems

must be performed to applicable codes and standards. Thermo Fisher Scientific assumes

no liability for the improper use of hydrogen as a carrier gas.

Preface

Hydrogen Safety Precautions

Thermo Scientific TSQ Series AutoSRM User Guide xv

• As with laboratory safety in general, be sure to wear safety glasses, laboratory coats,

gloves, etc. Typically there are no specific requirements for gaseous hydrogen, other than

eye protection when working with a compressed gas. If working with liquid (cryogenic)

hydrogen, insulated gloves and protective shoes should be worn in addition to eye

protection.

• You should post “No Smoking” and “No Open Flames” signs to identify hydrogen

sources and cylinders. Maintain, inspect and leak-test all hydrogen sources regularly.

• All hydrogen shutoff valves should be clearly marked and permanent hydrogen piping

should be labeled as such at the supply or discharge point and at regular intervals along its

length. Where hydrogen gas piping passes through a wall, the piping should be labeled on

both sides of the wall.

• There should also be contingency plans in place should an incident occur.

• The site emergency response team, as well as the local fire department, should know the

location of all hydrogen storage tanks.

Using Hydrogen with the Mass Spectrometer

To use hydrogen with the MS, you must always shut off the GC carrier gas before venting or

turning off the MS. There are three hydrogen safety screws on the MS that must be in place.

These are attached to your instrument at the factory.

Preface

Hydrogen Safety Precautions

xvi TSQ Series AutoSRM User Guide Thermo Scientific

Before powering on the MS system, ensure that:

• All the covers and panels of the MS system are firmly attached.

• The vent valve is tightly closed if you vented the system.

• All fittings, ferrules, and o-rings are sealed.

Hydrogen Connection Guidelines

Use the following guidelines to safely connect hydrogen to your system:

•Piping—Hydrogen must be delivered to equipment using appropriate piping and be

done in such a way as to pose essentially no hazard to end-users. Piping systems for the

delivery of hydrogen should be designed and installed by a person qualified by specific

training and experience with hydrogen piping systems.

Stainless steel is usually recommended because it is a safe, cost-effective material. Piping

of black iron or copper must not be used, as the pipe can become brittle with age.

Elastomeric/plastic tubing of various plastics and polymers should not be used, unless the

tubing is approved for use with hydrogen. If elastomeric/plastic tubing is used for

hydrogen gas delivery, the tubing should be tested for hydrogen permeability to minimize

leakage.

The hydrogen piping system must be flexible enough to endure routine thermal

expansion and contraction. The system should also include considerations for the most

severe condition of temperature and pressure expected during service. Piping and

supports must be able to withstand static loading introduced by such things as ice and

snow; and dynamic loading from high wind and earthquake.

Caution should be used if burying hydrogen piping. Proper controls should be used to

protect against damage and corrosion, and also to prevent Hydrogen from entering a

building if there is any leakage.

•Fittings—All fittings must be of the proper type approved or designed for use with

hydrogen gas. Use as few fittings as possible to minimize the potential for leaks. After

installation, ensure that leak testing is carried out prior to system use, and on a regular

basis.

There must be no PTFE tape or other things like plumber's putty used to enhance a seal, as

this actually is a detriment to a good seal. Ideally the best installation would use stainless

steel tubing with appropriate gas-tight fittings.

Welding is usually preferred for joints in hydrogen piping systems since welding provides

a better connection and reduces the potential for leaks compared to mechanical fittings.

Soft solder joints are not permitted for hydrogen systems (due to the low melting point of

soft solder and its potential for brittle failure at cryogenic temperatures). Brazed joints are

permitted, but such joints should be protected against the possibility of external fire.

Preface

Hydrogen Safety Precautions

Thermo Scientific TSQ Series AutoSRM User Guide xvii

Tubing connections should be clamped to barbed or press-fit type connections. Hose

clamps or jubilee clamps must not be used.

•Valves—All valves must be suitable for hydrogen service and for the specific operating

conditions. Valves, including regulators, must not be used for hydrogen, unless they are

designed and identified for such a use. Ball valves are often chosen because of their

superior leak tightness through the valve seat. Pneumatic operators are usually chosen for

remotely operated valves so that potential ignition sources (electricity) are remote from

the valve.

Manual shutoff valves should be provided near each point of use, within immediate reach.

If a hydrogen cylinder or hydrogen generation system is located within immediate reach,

a separate point-of-use shutoff valve is usually not necessary.

Line regulators that have their source away from the point of use should have a manual

shutoff valve near the point of use.

An emergency gas shutoff device in an accessible location outside the use area should be

provided in addition to the manual point-of-use valve in each educational and

instructional laboratory space that has a piped gas supply system.

If necessary, the piping system should have uninterruptible pressure relief. The pressure

relief system should be designed to provide a discharge rate sufficient to avoid further

pressure increase and should vent to a safe location outside or to a ventilation system

exhaust.

Purchasing Hydrogen

Use the following guidelines when purchasing hydrogen:

•Hydrogen Generator—Because it minimizes the amount of hydrogen present and

reduces the degree of hazard, a hydrogen generator (also called an electrolyzer) is the safest

way to purchase hydrogen in the quantity used in GC/MS.

However, to minimize the degree of hazard, the hydrogen generator must only be

operated in a non-explosive environment because hydrogen buildup can be ignitable.

This means that your ventilation system for the room or lab hood must maintain an air

exchange rate that is at least two orders of magnitude greater than the maximum

hydrogen production rate of the hydrogen generator. Be sure to follow the manufacturers'

directions about proper use and maintenance of the regulator.

To prevent the possibility of releasing hydrogen, the hydrogen generator should be set to

shut down if:

– There is a loss of flow to the ventilation system

– A hydrogen detector alarms at 25% of the lower flammable limit of hydrogen in air.

The oxygen exhausted by the electrolyzer should be vented to the outside as well.

Preface

Hydrogen Safety Precautions

xviii TSQ Series AutoSRM User Guide Thermo Scientific

•Hydrogen Cylinder—Hydrogen can be delivered in standard laboratory gas bottles or

cylinders. These cylinders have a limited amount of hydrogen in them and are a safe way

to transport and store hydrogen. However, compressed hydrogen gas cylinders, like all

compressed gas cylinders, must be secured in an upright position, ideally with a

non-combustible chain or cable. If the cylinder falls over, the valve can be knocked off

and the pressurized cylinder can take off like a rocket, which leads to the release of

hydrogen and possibly an explosion, severe injury, or death. Never crack a hydrogen

cylinder valve to remove dust or dirt from fittings prior to attaching a regulator, as there is

a risk of self-ignition.

Properly Storing Hydrogen

Storing and handling compressed hydrogen gas and cryogenic liquid hydrogen present

potential health and safety hazards. Using proper storage and handling techniques is essential

to maintaining a safe work environment.

Use the following guidelines when storing hydrogen:

• Store spare hydrogen gas cylinders outside and away from doors, windows, building air

intake vents, structures, and vehicle routes. This precaution applies when the hydrogen is

or is not in use. Indoor storage of spare hydrogen cylinders has special requirements,

which is beyond the scope of this document. Documentation for each vessel should

include a description of the vessel, a list of available drawings or other documents, the

most recent inspection results, and the responsible person's name.

• Prevent spare cylinders from toppling by wrapping them with chains. The chains should

also be protected against corrosion and excessive heat.

• Separate spare hydrogen cylinders from oxidizing gases (such as oxygen) with a 5 ft

(1.5 m) tall fire barrier with a half-hour fire rating or place the cylinders at least 20 ft

(6 m) apart.

• When moving hydrogen cylinders:

– Remove the regulator and replace the cylinder valve cap before moving.

– Move cylinders on cylinder carts or with other appropriate transport devices.

– Never roll or drop a cylinder and never lift a cylinder by its protective cap.

• Bulk hydrogen systems include either gaseous or liquid hydrogen in fixed installations; in

some gas systems a semi-permanent trailer (tube trailer) can be used. Storage vessels for

compressed hydrogen gas or liquid hydrogen should be designed, constructed, tested, and

maintained in accordance with applicable codes and standards. Bulk hydrogen systems

represent a level of complexity again which is beyond the scope of this document;

however some general guidelines are provided.

Preface

Hydrogen Safety Precautions

Thermo Scientific TSQ Series AutoSRM User Guide xix

• The bulk hydrogen storage system should not be located beneath electric power lines,

close to other flammable gases/liquids, or close to public areas. It should be readily

accessible to authorized personnel and delivery equipment, but protected from physical

damage or tampering.

• As liquid hydrogen systems also have a cryogenic hazard, additional safety considerations

for the use of cryogenic liquids might be necessary.

Hydrogen Safety Codes, Standards and References

Thermo Scientific TSQ Series AutoSRM User Guide 1

Using AutoSRM

This chapter tells you how to set up and run an AutoSRM discovery study. AutoSRM

discovery studies have three sections:

• The precursor ion study

• The product ion study

• SRM optimization

As well as instructions for setting up and running each study, this user guide gives you the

steps for importing the resulting transitions into the TSQ Series instrument method and

accessing them for routine use.

Determining Precursor Ions

The purpose of the first study is to select your precursor ions. During this study, after you

name your compounds and enter your vial numbers and retention times, AutoSRM instructs

your TSQ Series system to run a full-scan analysis on the compounds.

For precursor ion studies, along with the resulting chromatographic peaks and full-scan

spectra, AutoSRM presents you with a table of the most intense product ion masses that you

may select. If you wish, however, AutoSRM can automatically pick the product ion masses.

Note Set up your GC and autosampler methods through the Instrument Method Editor

in Chromeleon before developing your AutoSRM study.

26. By default, precursor ions are sorted by highest intensity. In the Precursor Ion Settings

box, you may select precursor ions according to the following criteria.

a. Number of Ions to Pick: Selects the number of precursor ions picked for each

compound.

b. Subtract Background: Checking this box subtracts background from the spectrum.

Subtracting the background may reduce baseline noise automatically away from the

selected peak. This will help identify your target compounds, clarify intensities, and

may reduce the effects of column bleed. If the automatic background subtraction is

not ideal (e.g., due to co-eluting peaks), you may select to manually subtract

background for individual compounds by right clicking on the chromatogram and

then highlighting the scan or scans to use for subtraction.

c. Intensity Thresholds: Allows you to select precursor ion candidates based on

intensity levels.

i. Absolute Intensity Threshold: Sets the minimum intensity level such that all

ions must be greater than this intensity to be selected as precursor ion candidates.

ii. Relative Intensity Threshold: Sets the minimum intensity of an ion relative to

the highest intensity ion to be a candidate for the precursor ion list. Ions must

have a relative abundance greater than or equal to this percentage to be selected

as precursor ion candidates.

d. Limit by m/z Range: Check this box and set the low m/z and high m/z to limit your

precursor ion selection list to certain masses within the set scan range.

e. Weighting Factors: Use the sliding bars and check boxes to set the values you want

to give each precursor ion study setting. The available factors are Intensity Weight

(peak height), Signal to Baseline Ratio (peak height/baseline height), and m/z. Set

the weights of each from 0 to 100, with a total weight of 100.

Tip When selecting precursor ions, you often get better results by weighting m/z

higher than intensity weight.

Now that you have selected your precursor masses, you can find the product masses.

AutoSRM instructs the TSQ Series system to acquire product ion scans of your precursor

masses at three collision energies. You do not have to set up any methods or sequences;

AutoSRM automatically does these for you. Also, the software instructs the autosampler to

make multiple injections if compound retention times are too close or if multiple precursor

ions are selected for a single compound.

Along with your chromatographic peak and your product ion spectra, AutoSRM presents you

with a table of the most intense product ion masses from which to choose. If you prefer,

AutoSRM can select the product ion masses for you.

4. By default, product ions are sorted by highest intensity. In the Product Ion Settings box,

you may select product ions according to the following criteria.

a. Number of Ions to Pick: Selects the number of product ions picked for each

compound.

b. Subtract Background: Checking this box subtracts background from the spectrum.

Subtracting the background may reduce baseline noise automatically away from the

selected peak. This will help identify your target compounds, clarify intensities, and

reduce the effects of column bleed. If the automatic background subtraction is not

ideal (e.g., due to co-eluting peaks), you may select to manually subtract background

for individual compounds by right clicking on the chromatogram and then

highlighting the scan or scans to use for subtraction.

c. Intensity Thresholds: Allows you to use intensity levels.

i. Absolute Intensity Threshold: Sets the minimum intensity level such that all

ions must be greater than this intensity to be selected as precursor ion candidates.

ii. Relative Intensity Threshold: Sets the minimum intensity of an ion relative to

the highest intensity ion to be a candidate for the precursor ion list. Ions must

have a relative abundance greater than or equal to this percentage to be selected

as precursor ion candidates.

d. Limit by m/z Range: Check this box and set the low m/z and high m/z to limit your

product ion selection list to certain masses within the set scan range.

e. Weighting Factors: Use the sliding bars and check boxes to set the values you want

to give each product ion study setting. The available factors are Intensity Weight

(peak height), Signal to Baseline Ratio (peak height/baseline height), and m/z. Set

the weights of each from 0 to 100, with a total weight of 100.

5. Review the product ion list and update the vial numbers if necessary.

6. Save the study by clicking the Save icon.

From this point you may export your transition list to your instrument method, or you may

send your selected transitions to an SRM optimization study for further optimization.

Developing the SRM Optimization Study

The final step in SRM development is the SRM optimization step. Now that you have

selected precursor and product masses, AutoSRM acquires those transitions at multiple

collision energies. Because of its fast scanning capabilities, the TSQ Series GC-MS system has

the ability to analyze three transitions per compound, each at 10 unique collision energies, in

a single injection.

Note AutoSRM lists product ions in order of highest energy intensity and at the optimal

collision energy for each product ion.

Tip AutoSRM automatically processes the data for you and suggests transitions if you

click the purple Auto Process icon.

To develop an SRM optimization study

1. Push the working list of precursor ions to the SRM optimization study.

2. Select Targeted or Full Range study in the SRM Energy Range drop-down box. See

Figure 28.

Targeted optimizations use a collision energy range that is 10 eV on either side of the

target energy in 2 eV steps. Full Range optimizations use collision energies from 5 to

50 eV in 5 eV steps.
