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

Chapter 6, Methods

, 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

Chapter 6,

Methods

, 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

section Chapter 3 on page 3-1

) or taken out of

Extended Standby (refer to

section 3.8.1 on page 3-61

), the HAPSITE will

automatically start preparing a Concentrator method. If the method that the
HAPSITE begins preparing is not the desired one, refer to

Section 5.3,

Selecting a New Method, on page 5-7

.

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

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

page 7-6

. When the final results message is displayed, click OK. See
