12 Hardware Installation
1 General Information
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.
WARNING
When using hydrogen (H
2
) as the carrier gas or fuel gas, be aware 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.
WARNING
The MSD 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.
