Abstract
The paper deals with the results of capillary columns implementation in vapor-phase chromatography. Glass and narrow-bore columns covered with liquid stationary phase and polyphenyl ether were used, the mixtures of aliphatic alcohols, acids, amines and ether derivatives of disulpho-benzoic acid, which are semi-products of additive synthesis analyzed. The usage of water vapor as a moving carrier of nitrogen enabled to decrease the analysis time and improve division efficiency. The retention time, height values of equivalent theoretic plates and coefficient of analyzed components asymmetry were calculated. Obtained results justify the practicability of glass capillary application for the analysis of disulpho-benzoic acid derivatives via vapor-phase chromatography method.
