  • HSA/CRA Develops New Method for Assessing Volatile Organic Compounds in Soil

    What is it? Modified Active Gas Sampling (MAGS) is an assessment tool, invented by HSA/CRA, which is effective at rapidly detecting unsaturated soil source areas impacted by volatile organic compounds. Rather than sampling tiny volumes of soil, we modified the traditional soil vapor sampling methodology to allow large volume sample collection. Combining commonly used equipment, a MAGS unit was ...

  • AQMesh can also be scaled using diffusion tubes

    The AQMesh team has carried out a test which shows that calibration (scaling) of AQMesh against one, or ideally several, diffusion tubes, is a viable option when no local reference station is available. When three AQMesh pods and four NO2 diffusion tubes were co-located against a reference station, the diffusion tube readings were so consistent with the reference average reading for the period ...
