5.4 Analyze (GC/MS) Mode with Concentrator
5.4.1 The Tri- Bed Concentrator
This method is used for analyzing samples with concentration levels in the low part
per billion to high part per trillion range. It is used when a compound is suspected,
but Survey does not show an increase in TIC count. See
, for
additional information on Analyze (GC/MS) methods.
5.4.2 The Tenax Concentrator
This method is also used for analyzing samples with concentration levels in the low
part per billion to high part per trillion range. The Tenax’s use is similar to that of the
Tri-Bed. However, the Tenax concentrator will not effectively concentrate
compounds with boiling points below 80 degrees Centigrade. See
, for additional information on Analyze (GC/MS) methods.
For help installing the Concentrator, refer to
Section 2.7.1, Installing the Tri-Bed or
Tenax Concentrator, on page 2-27
for instructions. Once installed, the
Concentrator must be cleaned before sampling begins.
1
Verify that the Concentrator is installed.

When powered on (refer to
) or taken out of
Extended Standby (refer to
), the HAPSITE will
automatically start preparing a Concentrator method. If the method that the
HAPSITE begins preparing is not the desired one, refer to
Selecting a New Method, on page 5-7
.
3
Power on the Laptop by pushing the Power button. Open ER IQ Software by
double-clicking on the ER IQ Icon. See
Figure 5-13 ER IQ Software Icon

The HAPSITE will begin preparing to run the default Concentrator method. It
will heat all necessary components, check pressures and run an AutoTune if
necessary. Progress of the preparation will be shown as a bar graph on the
Laptop screen. If AutoTune fails, refer to
Section 7.4, AutoTune Failure, on
. When the final results message is displayed, click OK. See
Figure 5-14 AutoTune Complete
