FIELD: analytic chemistry. SUBSTANCE: method involves taking a sample, putting it into the evaporator of a gas chromatograph wherein the temperature is 35-45 C higher than the boiling point of the component with the highest boiling point. Then volatile components are extracted by a flow of gas carrier and the quantity of emitted volatile components is determined. Before putting the sample into the evaporator, it is homogenized by treating it with one of inert fillers such as starch, talc or kaolin. EFFECT: higher efficiency. 4 cl, 4 dwg, 4 tbl
