摘要
Cyclodextrins linked to silica gel are used as gas-solid chromatographic stationary phases. They provide an effective means for separating a wide variety of gases. Evaluation of different cyclodextrin columns and the analogous silica gel support column with inorganic gas standards is reported. Separation selectivities and efficiencies differ between silica gel and the cyclodextrin phases. Capacity factors and chromatograms are presented for these gas-solid chromatographic stationary phases. The native cyclodextrin stationary phases appear to retain gases via at least two different retention mechanisms.
