| Short description: |
A membrane interface probe (MIP) is a
semi-quantitative, field-screening device that can detect
volatile organic compounds (VOCs) in soil and sediment. It is
used in conjunction with a direct push platform (DPP), such as a
cone penetrometer testing rig (CPT) or a rig that uses a
hydraulic or pneumatic hammer to drive the MIP to the depth of
interest to collect samples of vaporized compounds. The probe
captures the vapor sample, and a carrier gas transports the
sample to the surface for analysis by a variety of field or
laboratory analytical methods. Additional sensors may be added
to the probe to facilitate soil logging and identify contaminant
concentrations. The results produced by a MIP at any location
are relative and subject to analytic verification.
