Fused-silica open-tubular capillary columns coated with high-molecular-weight polyethylene glycols of different origins have been evaluated. The chromatographic behaviour below and above the solid-liquid transition temperature was studied through measurements of the column efficiency, resolution and capacity factors as a function of the column temperature and the nature of the solutes.

AbstractDue to their high polarity and unique selectivity, cyanopropyl silicones are basic stationary phases for high resolution capillary gas chromatography. Different OH‐terminated cyanopropyl silicones, containing a high cyanopropyl content, were synthesized and chromatographically evaluated. Special attention was paid to the degree of immobilization of the phases in FSOT columns. Depending on the problem at hand, a choice has to be made between immobilization and maximum selectivity.
