Precautions
26 5977C GC/MSD Operating Manual
General laboratory precautions
Avoid leaks in the carrier gas lines. Use leak-checking equipment to
periodically check for hydrogen leaks.
Eliminate as many ignition sources from your laboratory as possible (open
flames, devices that can spark, sources of static electricity, etc.).
Do not allow hydrogen from a high pressure cylinder to vent directly to
atmosphere (danger of self-ignition).
Use a hydrogen generator instead of bottled hydrogen.
Operating precautions
Turn off the hydrogen at its source every time you shut down the GC or MSD.
Turn off the hydrogen at its source every time you vent the MSD. (Do not heat
the capillary column without carrier gas flow.)
Turn off the hydrogen at its source every time shutoff valves in an MSD are
closed. (Do not heat the capillary column without carrier gas flow.)
Turn off the hydrogen at its source if a power failure occurs.
If a power failure occurs while the GC/MSD system is unattended, even if the
system has restarted by itself:
1 Immediately turn off the hydrogen at its source.
2 Turn off the GC.
3 Turn off the MSD, and allow it to cool for 1 hour.
4 Eliminate all potential sources of ignition in the room.
5 Open the vacuum manifold of the MSD to atmosphere.
6 Wait at least 10 minutes to allow any hydrogen to dissipate.
WARNING
GC configuration:
Ensure hydrogen is configured in the firmware for all gas channels using
hydrogen. An EPC that is not configured for hydrogen when hydrogen is
used could affect the hydrogen safety portion of the GC.
Ensure all column connection(s) are configured correctly on the GC
firmware, especially for any connection(s) to the MS system.
When available, ensure LVDS cable is connected to GC. This tells the GC
to shut off carrier gas if the MS has a pump failure or is powered off.
