|
| Advanced Gas Leak Detector Specifically Configured for Vapor Well Intrusion The new GasCheck G2 He utilizes an advanced micro-thermal conductivity sensor with improved sensitivity for rapid, effective detection of Helium down to ppm levels. |
| Features: |
• Improved Micro Thermal Conductivity
Sensor for enhanced sensitivity • Readings in ppm • New graphical icon display menu • Rapid detection, particularly sensitive to helium • Reliable, stable and repeatable readings • Conveniently calibrated against helium • LCD back lit display • Hand held & robust |
Historically, when collecting soil
vapor samples as part of a vapor
intrusion evaluation, there has been
no way to identify whether a soil
sample has been diluted by ambient
air. The use of a tracer gas has
introduced a QA/QC measure to verify
the integrity of the soil vapor probe
seal. Typically, helium is used as a
tracer because it is readily available,
non-toxic and can be monitored with
a portable detector. The preferred
scenario for use of a tracer gas is to
use a portable monitoring device to
analyze a sample of soil vapor for the
tracer before and after sampling for
the compounds of interest. The
advantage of this method is that
tracer sampling results can be used
in real time to confirm the integrity of
the probe seals. |
