5. You must provide the gas supplies for your GC-GC/MS system. Be sure to order your
gases and regulators far enough ahead of time to have them ready for the installation
process.
6. You will need a supply of ultra-high purity GC gas. Typical cylinders are about 23 cm (9
in.) wide by 140 cm (55 in.) tall and output >15,000 kPa (>2200 psig).
A single full-size tank contains 8000 L of helium or 6000 L of hydrogen and each will last
about three months with a typical usage rate of 50 mL/min.
WARNING Before using gases, carefully read the hazard indications and information
reported in the Safety Sheet supplied by the manufacturer referring to the CAS (Chemical
Abstract Service) number. It is the user’s responsibility to see that all local safety
regulations for the use of gases are obeyed.
CAUTION
Secure gas cylinders to an immovable structure or wall. Handle all gases
according to local safety regulations.
WARNING - EXPLOSION 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.
All Thermo Fisher Scientific gas chromatographs normally uses an inert gas as carrier gas.
If you wish to use hydrogen as a carrier gas, the hydrogen sensor must be installed into the
oven of your GC. Contact a Thermo Fisher Scientific sales representative if you plan to
use hydrogen as the carrier gas in your GC. If you don’t have the hydrogen sensor, you
must
use an inert carrier gas.

1 .
Ultra-high purity with less than 1.0 ppm each of water, oxygen, and total hydrocarbons and contained in one
tank. Impurities below 1.0 ppm generally do not require purification. Gases with higher impurity levels may require
the use of appropriate water, oxygen and hydrocarbon traps.

Connectors will vary with cylinder size. Confirm that your regulator will work with your gas tank. All connections
to the TriPlus 300 are 1/8 in. Swagelok fittings.
