Figure 11-18 Scan Events
The Filament Delay is a delay, after the start of analysis, which must pass before
the filament is turned on. This delay should be set as a protection for the filament;
enough delay should be set to allow the components of the air peak or solvents to
pass through the Mass Spectrometer before turning the filament on.
HINT: In some applications, if the Mass Spectrometer starts collection of data too
soon, then the high pressure burst caused by a solvent peak may shut
down the Mass Spectrometer and stop the analysis.
The Run Time is calculated based on the Inlet Events and GC Temperature
Profiles and is the cumulative time of the Method.
11.4.5 Concentrator Selection
There are three selections available for the Concentrator:
None . . . . . . . . . . . . . . . . . . . . . . . . Select this when no concentrator will be used
with this Method.
Carbon. . . . . . . . . . . . . . . . . . . . . . . Select this when a Tri-Bed or Carbopack
concentrator will be used with this Method.
Tenax . . . . . . . . . . . . . . . . . . . . . . . . Select this when a Tenax concentrator will be
used with this Method.
11.4.6 Headspace Flow Parameter
Headspace Flow Pressure controls the flow rate of nitrogen through the HSS
during the Sample and Purge states. This parameter is only available when the
HSS is used.
