3.6 GC/MS Mode with Tenax Concentrator
This method is used for analyzing samples with concentration levels in the low part
per billion to high part per trillion range. This method is used when the loop method
fails to detect a chemical and is similar to the Tri-Bed concentrator method. The
Tenax concentrator will not effectively concentrate compounds with boiling points
below 80 degrees Centigrade. Refer to Chapter 6, Methods, for additional
information on GC/MS methods.
NOTE: Before a GC/MS can be run in this Concentrator mode, the Tenax
concentrator must be installed. Refer to Section 2.9.4, Installing the Tenax
or Carbopack Concentrator, on page 2-31 for instructions. Once installed,
the Tenax concentrator must be cleaned before sampling begins.
