gas can flow into the GC 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.
Hydrogen use is specifically prohibited with the 7200 or 7250 GC/Q-TOF system.
