Operating Guide
The GC has three operating keys.
[Stop]
Immediately terminates the run. If the GC is in
the middle of a run, the data from that run
may be lost. Refer to the
for information on how to restart the GC after
pressing [Stop].
[Prep Run]
Activates processes required to bring the GC to
the starting condition dictated by the method
(such as turning off the inlet purge flow for a
splitless injection or restoring normal flow
from gas saver mode).
[Start] Starts a run after manually injecting a sample.
(When you are using an automatic liquid
sampler or gas sampling valve, the run is
automatically activated at the appropriate
time.)
Scrolls up and down through the display one
line at a time. Use to view:
• Remaining run time
• Next run time
• Current status messages (what the GC is
doing)
• Current temperatures, pressures, and flows
• Valve state
• GC firmware revision
• GC IP address
