Hydrogen gas may be used as carrier gas, and/or as fuel for the
FID. When mixed with air, hydrogen can form explosive
mixtures.
When using hydrogen (H
that hydrogen gas can flow into the oven and create an explosion
hazard. Therefore, be sure that the supply is off until all connections
are made, and ensure that the inlet and detector column fittings are
either connected to a column or capped at all times when hydrogen
gas is supplied to the instrument.
Hydrogen is flammable. Leaks, when confined in an enclosed space,
may create a fire or explosion hazard. In any application using
hydrogen, leak test all connections, lines, and valves before
operating the instrument. Always turn off the hydrogen supply at its
source before working on the instrument.
The GC cannot detect leaks in inlet and/or detector gas streams. For
this reason, it is vital that column fittings should always be either
connected to a column, or have a cap or plug installed.
When using hydrogen gas, check the system for leaks to prevent
possible fire and explosion hazards based on local
Environmental Health and Safety (EHS) requirements. Always
check for leaks after changing a tank or servicing the gas lines.
Always make sure the vent line is vented into a fume hood.
