Gas chromatographic study of sorption properties of mixed polymer phase containing acetylated β-cyclodextrin

Abstract

In work was studied sorption of organic compounds of different classes, including some of the
optical isomers, by gas-liquid chromatography, by polymeric phase polydimethylsiloxane PMS-100 and
mixed phase "PMS-100 - heptakis(2,3,6-O-acetyl)-β-cyclodextrin». It is shown that the additive chiral
macrocyclic compound promotes strengthening of intermolecular interactions «sorbate - stationary
phase» at the expense of formation of complexes on type «guest - host» for small molecules on the size of
organic compounds, and also causes moderated enantioselective properties of the investigated sorbent.
