Quick Reference 11
The Run 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 Agilent 7890A GC Advanced User
Guide 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 injec-
tion 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 acti-
vated at the appropriate time.)
