A capillary column for gas chromatography was prepared using microspherical particles of hypercrosslinked polystyrene. The hypercrosslinked stationary phase approximates the stationary phases based on the poly(trimethylsilylpropyne) membrane polymer

The possibility is verified of estimating the phase ratio of a chromatographic column chromatographically from the semi-empirical dependence of the retention time of homologs on the number of carbon atoms in their structure. The effect the nature and

Different ways of estimating the hold-up time of a system in gas chromatography are considered. It is shown that the hold-up time found from aerodynamic dependences proves to be minimal, but does not allow for the contribution from extracolumnar effe

Changes in retention factor k of light hydrocarbons on PIM-1 stationary phase with an increase of ageing temperature are tested. Varying the ageing temperature from 50 to 200°C causes a slight decrease in solute retention, which, however, changes to

Chromatographic determination of the thermodynamic parameters of sorption for light hydrocarbons retention on a stationary phase based on poly [trimethylsilyl (propyn-1)] (PTMSP) was performed and the effect of column preheating at temperatures up to

Polyimide PIM-1, which forms a porous polymer layer on the walls of a capillary column, exhibits high thermal stability. It is studied as a stationary phase for gas chromatography. A column with the PIM-1 stationary phase displays a drastic differenc

The thermal stability of poly[1-(trimethylsilyl)-1-propyne] is studied by heating a capillary column containing the polymer as a stationary phase and systematically separating a test mixture of light hydrocarbons on the column. It is shown that heati
