In 2013, Amplified Geochemical Imaging LLC (AGI) acquired the GORE® Survey Products Group, maker of the GORE-Sorber. The AGI Sampler (formerly the GORE-Sorber) is a proprietary adsorbent that collects volatile and semi-volatile compounds present in air, soil gas, and water. The adsorbents are sealed inside a tube of microporous expanded polytetraflouoethlene (ePTFE), more commonly known as the membrane.
W.L. Gore & Associates, Inc. supplies AGI specialized quality material used in the manufacturing of our AGI Passive Samplers. The unique membrane is water repellent but allows for the free diffusion of gases to penetrate the sampler and collect on the adsorbent material. This ability to protect sample integrity from contact with soil, water, and organic material makes it easy to use in virtually any site condition.
