HAPSITE Smart Plus Operating Manual

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 it
down 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 at the point of sample injection
onto the GC column.

WARNING

Only trained users should modify methods. If the
incorrect Concentrator is selected when creating a
method the detection limit may not provide the correct
concentration of the media.

11.5.5 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 Concentrator will

be used with this Method.

Tenax . . . . . . . . . . . . . . . . . . . . . . . . Select this when a Tenax Concentrator will

be used with this Method.

11.5.6 Headspace Flow Parameter

WARNING

Only trained users should modify methods. Incorrect
flow rates may lead to improper analysis.

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.
