Survey . . . . . . . . . . . . . . . . . . . . . . . This Inlet State sets the GC valves and turns
on the sampling pump so the sample will
by-pass the GC and be directed to the inlet of
the MS for real time analysis.
NOTE: Survey is the Inlet State used (by
default) in the Survey and Direct
Sample, Single Compound
Methods. This cannot be changed.
Other . . . . . . . . . . . . . . . . . . . . . . . . This allows the customization of each
specific GC valve for a custom GC valve
state. Useful for GC troubleshooting.
Standby . . . . . . . . . . . . . . . . . . . . . . This Inlet State must be included in every
Method as the last state. Standby closes the
Membrane Isolation valve and turns the
Mass Spectrometer filament off.
The following Inlet States are available in the Inlet States column when a
Concentrator is being used:
ConcFill . . . . . . . . . . . . . . . . . . . . . . Equivalent to loopfill when a concentrator is
used.
ConcCooldown. . . . . . . . . . . . . . . . This Inlet State provides a duration of time
that lets the concentrator cool down to a
desired operating temperature.
Line Purge. . . . . . . . . . . . . . . . . . . . This Inlet State pulls the sample through the
probe and out through the exhaust vent. The
sample does not go through the
concentrator.
PreDesorb . . . . . . . . . . . . . . . . . . . . PreDesorb begins the process of removing
the analytes adsorbed on the concentrator
and moving them to the instrument for
analysis.
Desorb. . . . . . . . . . . . . . . . . . . . . . . This completes the desorption of analytes off
the concentrator and into the GC.
The following Inlet States are only available in the Inlet States column when the
HSS is enabled for use:
HSSample . . . . . . . . . . . . . . . . . . . . This Inlet State sets the valves of both the
HAPSITE and HSS and turns on the sample
pump for collecting a sample for GC/MS
analysis. This passes the headspace of the
sample through the transfer line and to the
HAPSITE Analytical module.
