3.8 GC/MS Mode with Headspace Sampling System and
Concentrator in Portable Mode
This method is used for analyzing samples with concentration levels in the low part
per trillion range. This method is used when the loop method fails to detect a
chemical. Refer to
for additional information on GC/MS
methods.
CAUTION
The concentrator feature is designed to enhance
HAPSITE sensitivity when analyzing low concentration
samples. The accumulated sample VOCs are transferred
from the concentrator adsorbent bed to the HAPSITE as
a concentrated sample. Care should be taken to avoid
overloading the HAPSITE and causing excessive
carryover of VOCs in subsequent runs.
