FIELD: analytical methods.
SUBSTANCE: invention relates to gas analysis of mixtures allowing performing complete separation of components of gas-liquid mixture composed by air, carbon dioxide, saturated and unsaturated hydrocarbons, water, acetaldehyde, acroleine, propylene oxide, and acetone under temperature programming. Method is based on utilizing chromatographic column filled with sorbent constituted by nonpolar Chromosorb 106 and polar modified Haye Sep N taken at ratio 50:50. Mixture to be analyzed is first directed on modified Haye Sep N and then on Chromosorb 106.
EFFECT: increased selectivity of chromatographic column.
