This 36-page e-book from Markes International describes the role of thermal desorption (TD) for assess volatile and semi-volatile organic compounds (VOCs and SVOCs) in ambient air, whether outdoors or within buildings. The main sampling techniques described are set in the context of national and international regulations, and include passive (diffusive) and pumped (active) sampling on to sorbent tubes, on-line monitoring of air/gas streams, and pre-concentration of canister samples. Covering a range of key applications from urban air monitoring to soil-gas analysis, this guide will prove invaluable to any environmental analyst.
