FIELD: analytical chemistry. SUBSTANCE: method involves preliminary sample selection on carbon fibrous sorbent followed by desorption in mixture of air and distilled water. Distilled water for desorption is taken at amount 0.07-0.15% of gas sample volume which is fed in chromatograph. Desorption process is carried out under normal pressure in nonsealed system. EFFECT: improved method of analysis. 2 cl, 1 dwg
