Abstract: New technique, allowing to increase the accuracy of determination of molecular weight and boiling temperature of unknown components of analyzing mixture, in comparison with our work described in the journal ”Sorption and Chromatographic Processes” 2011, № 4 and based on information on sizes of indexes of retention of Van den Dool and Krats and indexes of the logarithm of constant of distribution in the system ”hexane–acetonitrile”is suggested.

Keywords: gas chromatography, temperature programming, retention indexes, chromate-distributive method, molecular weight, boiling temperature, identification.
