Abstract
The technique of chromatography is presented which enables to combine chromatographic separation and identification of organic compounds, containing double-bonds. The method is based on different chromatographic mobility of Z- and E-isomers. Isomerization is carried out by direct surface UV-light irradiation on sorbent. This method can be successfully applied to identification of aromatic azo- and azoxycompounds, stilbene derivatives and unsaturated acids.
