Abstract

Cyclodextrin, bonded to silica gel and used as a gas-solid chromatographic (GSC) stationary phase provides a practical and efficient means for separating a wide variety of volatile C1-C7 hydrocarbons at ambient to elevated temperatures. Conditioning the columns at high temperature (300°C) for several hours increased efficiency and resolution. The adsorption of these light hydrocarbons involves multiple retention mechanismns. For unsaturated hydrocarbons, the cyclodextrin GSC column can act as a polar stationary phase analogous to silica gel. However, for saturated hydrocarbons, it acts as a non-polar phase. Evaluation of the columns and an analogous silica gel column with hydrocarbon standards is reported. Capacity factors and chromatograms are presented for compounds analyzed on these GSC stationary phases. © 1993.
