The Membrane Interface Probe (MIP) is a High-Resolution Vertical Mapping tool which Numac offers to detect in real time subsurface contamination for environmental site assessments and characterizations, specifically volatile organic compounds (VOCs) such as halogenated solvents, petroleum compounds, and methane.The MIP is a multipurpose tool for mapping soil and groundwater contamination, specifically VOCs such as halogenated solvents and petroleum compounds. As a continuous VOC sampling system which heats the soil, water, and vapor matrix as it is driven into the subsurface, the MIP maps contaminants within the groundwater and the surrounding soil. The VOC mass which is extracted across a semi-permeable membrane is carried to the surface by an inert purge gas via small diameter inert tubing. Once the compounds reach the surface they are analyzed by a suite of three laboratory grade detectors.
