Soil probes

VOC-Mole

P-00001

VOC-Mole is a stainless steel assembly that is inserted into the ground, allowing soil gas to be sampled onto a sorbent tube, for analysis using thermal desorption (TD). VOC-Mole is constructed from stainless steel drilled with a series of holes through which soil gases can pass. The probe has a tapered tip, which allows it to be driven into the ground using the dedicated impact former.

  • Robust and easy to transport
  • Compatible with passive and pumped sampling
  • Can be left in situ for long periods
  • Cap prevents ingress of water, wildlife and soil debris

Overview

Three probe lengths are available for sampling volatiles at different depths:

  • 295 mm (11.6 inches)
  • 445 mm (17.5 inches)
  • 895 mm (35.2 inches)

Versatile sampling options

VOC-Mole uses an aluminium sampling cap to prevent the ingress of water, wildlife and general soil debris, and is easily adapted to two sampling modes:

  • Passive sampling onto single-bed sorbent tubes is the best option for large-scale monitoring over periods of 1 day to several weeks. In this configuration, the tube is fitted to the lower end of the cap assembly, which is then lowered into the VOC-Mole body. The hole at the top of the assembly is covered with a blanking cap.
  • Pumped sampling onto single-bed or multi-bed sorbent tubes is suitable for sampling over periods of up to 8 hours and is especially useful for monitoring a broad analyte range in a single run. Typically, the tube configuration is the same as for passive sampling, with a low-flow pump attached to the hole in the cap.

Alternatively, the tube and pump can be placed entirely outside the VOC-Mole body. Tube and sampling cap assemblies can be prepared in the laboratory and sealed ready for transport to the field (where the probes may already be in situ).

VOC-Mole has a number of applications, ranging from mapping of contaminated land prior to remediation to forensic investigations and chemical ecology studies of soil microorganisms.

  • Surveys of industrial, waste and brownfield sites
  • Emissions from soil-borne microorganisms
  • Pinpointing of leaks from pipelines

As well as GC analysis of tubes, hand-held PID or FID detectors can be used with VOC-Mole for quick screening of vapour levels.
