HAPSITE ER Operating Manual
Survey . . . . . . . . . . . . . . . . . . . . . . . Turns on the sampling pump and directs the
sample to the inlet of the MS.
Other . . . . . . . . . . . . . . . . . . . . . . . . Customizes each specific GC valve for a
custom GC valve state. Useful for GC
troubleshooting.
Standby . . . . . . . . . . . . . . . . . . . . . . Standby is the last state of every method.
Standby closes the Membrane Isolation
valve and turns off the MS filament.
The following additional Inlet States are available in the Inlet States column when
a sample loop is being used:
Loopfill . . . . . . . . . . . . . . . . . . . . . . Controls the sample pump and directs the
sample through the sample loop.
The following additional Inlet States are available in the Inlet States column when
a concentrator is being used:
ConcFill . . . . . . . . . . . . . . . . . . . . . . . Controls the sample pump. This step directs
the sample through the concentrator to allow
the analytes to absorb to the concentrator bed.
ConcCooldown . . . . . . . . . . . . . . . . The concentrator is cooled to a desired
operating temperature.
PreDesorb . . . . . . . . . . . . . . . . . . . . PreDesorb starts the desorption of analytes
from the concentrator process.
Desorb . . . . . . . . . . . . . . . . . . . . . . . Completes the analyte desorption process.
This state directs the analytes to the GC
column.
The following Inlet States are only available in the Inlet States column when the
HSS is enabled for use:
HSSample . . . . . . . . . . . . . . . . . . . . Turns on the sample pump to direct sample
through the transfer line to the HAPSITE ER.
The suggested HSSample duration is
approximately 15 seconds.
HSPurge . . . . . . . . . . . . . . . . . . . . . Directs carrier gas flow through the lines, the
needle assembly and the transfer line to
remove moisture and clean out the previous
sample.
HSConcDry . . . . . . . . . . . . . . . . . . . Directs carrier gas flow through the transfer
line and concentrator to remove moisture
prior to sample injection. This should only be
used if the HSS is connected to an external
cylinder of carrier gas.
