HSConcDry . . . . . . . . . . . . . . . . . . . This Inlet State allows dry N
2
gas to flow
through the Transfer Line and Concentrator
to remove moisture prior to sample injection.
This should only be used if the Headspace
system is connected to an external cylinder
of Carrier Gas.
The following Inlet States are only available in the Inlet States column when the
SituProbe is enabled for use:
SPLinePurge. . . . . . . . . . . . . . . . . . This state sets the valves for Nitrogen to flow
through the lines and SituProbe assembly,
then through the Transfer Line. The
recommended event duration is at least 60
seconds to allow for clearing the sample line
of carryover and to mix the sample with
Internal Standard (if used).
SPConcFill . . . . . . . . . . . . . . . . . . . This sets the GC valves so that the sample
pump pulls the sample through the
Concentrator.
SPLoopFill . . . . . . . . . . . . . . . . . . . This sets the GC valves so that the sample
pump pulls the sample through the Sample
Loop. The recommended duration is at least
60 seconds to allow for clearing the sample
line of the previous sample as well as good
mixing with the Internal Standard (if used).
SPN

DryPurge . . . . . . . . . . . . . . . . This Inlet State purges the Transfer Line and
Concentrator system with dry N
2
before
sample injection to remove moisture.
