T
he Purge and Trap Apparatus* is widely used
for the isolation of pollutants in soil, sediment,
waste water, and other solid and liquid samples by
purging a clean gas over and thru the sample contained there-
in and trapping the purged volatiles on adsorbent traps. This
device has been modified by S.I.S. to trap these volatiles on the
S.I.S. GLT Thermal Desorption Tubes. The 1000 ml version of this
apparatus can purge and trap benzene in water down to 1 ppb
using conventional GC or GC/MS techniques.
A variety of purge gas tubes can be used including a plain 1/4"
diameter glass tube, 1/4" stainless steel tube, or the diffusion tube
which includes a fine frit on the end of the tube to deliver the purge
gas in small bubbles to better purge the volatiles from liquid sam-
ples. These tubes can be fitted to the purge gas source via
Swagelok connectors with PTFE ferrules or via inert plastic tubing.
The S.I.S. GLT Thermal Desorption tubes are screwed into the
adapter fitting and a seal made via the standard PTFE washers.
This adapter in turn fits into the plastic adapter on the Wheaton
glassware.
The systems include glass vessel and all fittings as shown
including adapter (781011), GLT tube, PTFE seal and S.S. cap with
hole (781007).
