Volatile organic compound sampler ø 45 mm | G.A.B.I.E.

for gas chromatographycompact

The G.A.B.I.E. badge (Gas Adsorbent Badge for Individual Exposure) is a passive sampler developed by INERIS (French National Institute for Research and Safety), which allows simultaneously sampling of a multitude of organic gases and vapors in order to determine Average Exposure Values (TWA). Principle The volatile organic compounds (VOC) in the atmosphere are captured by diffusion at specific rates unique to the substances and the badge’s geometry. They are then trapped in an adsorbent material (activated charcoal) located in the bottom of the badge. Sampling begins as soon as the badge is opened and attached in the workers’ respiratory zone. At the end of collection, the badge? must be closed and sent immediately to the laboratory, which performs the desorption of the pollutants using a solvent and then analyzes the solution obtained. The reliability of the G.A.B.I.E. has been the subject of many tests following a rigorous protocol complying with the criteria of European standard EN 838 to guarantee its performance. This protocol allows you to verify the coherence of the sampling rates over given ranges of variation of airspeed, temperature, relative humidity and concentration of pollutant(s).? Main features: - Allows you to sample up to 175 type of VOCs, for which the activated charcoal method is used - B-type sampler, in accordance with European standards EN 838, 1995. - Ideal for occasional checks or for campaigns which involve many workers at the same time - Lightweight and compact: doesn’t hinder the worker in his activity - Assures representative sampling regarding individual exposure - Easy to use: it can be used anywhere
