Adsorbents used to analyze air for concentrations of various organic compounds with their subsequent determination by thermal desorption gas chromatography–mass spectrometry (GC–MS) are considered. Tenax-TA is the most commonly used material for such tasks, but it has drawbacks. The characteristics of adsorbents of Tenax, Carbosieve, Carboxen, Carbotrap, Capbopack, Porapak, Chromosorb families, XAD polymer resins, activated carbons, and some monolithic carbon materials are given. Their advantages and disadvantages for the adsorption/thermal desorption of hydrocarbons are discussed. The advantages of monolithic carbon materials and the need in the development of a new domestic material for analytical gas chromatography–thermal desorption mass spectrometry in solving oil-prospecting problems are substantiated.
