gas can flow into the GC oven and create an explosion hazard. Therefore, be sure
that the supply is turned off until all connections are made and ensure 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.
Please refer to the Hydrogen Safety Guide shipped with your instrument.
