5.5 Analyze (GC/MS) Mode with Concentrator

5.5.1 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.

5.5.2 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.

WARNING

The Tenax Concentrator cannot detect compounds with
boiling points below 80 degrees centigrade.

For help installing the Concentrator, refer to

Section 2.10.3, Installing the Tri-Bed

or Tenax Concentrator, on page 2-34

for instructions. Once installed, the

Concentrator must be cleaned before sampling begins.

During the preparation, the HAPSITE 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
