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.

Hydrogen Safety Precautions
Thermo Scientific TSQ 8000 Evo AutoSRM User Guide xiii
Hydrogen Safety Precautions
Hydrogen is a colorless, odorless, highly flammable gas with the molecular formula H2and 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.
READ MANUAL: Alerts you to carefully read your instrument’s
documentation to ensure your safety and the instrument’s operational
ability. Failing to carefully read the documentation could or might put you at
risk for a physical injury.
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
xiv TSQ 8000 Evo AutoSRM User Guide Thermo Scientific
• 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 SpectrometerTSQ 8000 Evo
To use hydrogen with the TSQ 8000 Evo, you must always shut off the GC carrier gas before
venting or turning off the TSQ 8000Evo. There are three hydrogen safety screws on the
TSQ 8000 Evo that must be in place. These are attached to your instrument at the factory.
Figure 1. Hydrogen Safety Screws on the TSQ 8000 Evo

• 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.
Tubing connections should be clamped to barbed or press-fit type connections. Hose
clamps or jubilee clamps must not be used.

Preface
Hydrogen Safety Precautions
xvi TSQ 8000 Evo AutoSRM User Guide Thermo Scientific
•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
Thermo Scientific TSQ 8000 Evo AutoSRM User Guide xvii
•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
xviii TSQ 8000 Evo AutoSRM User Guide Thermo Scientific
• 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.
