摘要：

Modification of adsorption open capillary columns coated with polytrimethylsilylpropine (PTMSP) was experimentally studied. The modification of PTMSP by solvents (chlorobenzene, pentanol) and hot ethanol improves (up to 40%) the efficiency of capillary columns with a slight (3-7%) decrease in the retention factor.
