Study of the adsorption effects at the surface of poly-(ethylene glycol)-coated column packings

Gas chromatographic data for a series of solutes on a purified dimethoxypoly-(ethylene glycol) are presented. The retention volumes were measured on columns prepared with two supports, one wettable and the other partially wettable by the stationary phase, at four temperatures and on four column pack...

Description
Summary:Gas chromatographic data for a series of solutes on a purified dimethoxypoly-(ethylene glycol) are presented. The retention volumes were measured on columns prepared with two supports, one wettable and the other partially wettable by the stationary phase, at four temperatures and on four column packings with different loadings. The data permitted the evaluation of equilibrium parameters characterizing solute absorption in the stationary phase and solute adsorption at the different interfaces in the column. An attempt to interpret the results is described.
