Mi BMVM2
Contaminated Land?
Pollution tracking?
Monitoring underground leakage?
The VOC-Mole™ from Markes International offers
low-cost soil screening of large commercial, waste
and brownfield sites for all common volatile and
semi-volatile organics.
Moles are arranged in a grid pattern over key areas of
a site. Organic pollutants migrate into the hollow
stainless steel probes and are collected diffusively or
using pumps onto sorbent tubes. Subsequent
analysis is via thermal desorption-gas
chromatography and all measurements are relative.
Leaks, spills and contamination hotspots may be
quickly pinpointed and the plume or flow of
contamination tracked.
VOC-Mole™
The VOC-Mole Soil Probe is available in three probe
lengths; 11¾-inch; 18-inch and 36-inch. Its unique
aluminium sampling cap is an Mi™ copyrighted design
which renders the probe suitable for both diffusive
and pumped sampling. An industry standard diffusive
sampler can be connected inside the probe, while
tubing for pumped samplers may be attached to the
external connector. This allows a variety of different
sampling regimes to be undertaken, for example:
• standard diffusive monitoring over a long time
period (i.e. 24 hours)
• pumped monitoring with the sample tube
placed within or outside the probe
• the connection of two tubes in series, one
inside, one outside the probe body, to monitor
potential breakthrough of highly volatile
components.
The sampling cap contains double Viton® O-Ring
seals to prevent the ingress of water, wildlife and
general soil debris.
Tube and sampling cap assemblies may be prepared
in the laboratory, and sealed ready for transportation
to the field, where the probes may already be in situ.
Accessories
Two accessories are available for use with the VOCMole.
