IMMOBILIZATION OF YLDIMETHYLSILYL-2,3-DI-O-METHYL)-BETA-CYCLODEXTRIN FOR CAPILLARY-GAS-CHROMATOGRAPHY AND SUPERCRITICAL-FLUID CHROMATOGRAPHY AND MICRO-LIQUID-CHROMATOGRAPHY

yldimethylsilyl-2,3-di-O-methyl)-beta-cyclodextrin was monofunctionali zed by the introduction of linker-groups into the 2-, 3-, and 6-positi ons of the glucose monomer. The selectively modified cyclodextrin was bonded to dimethylpolysiloxane and immobilized to fused silica capilla ries. It was also linked to aminopropyl silica by the formation of an amide bond. The new chiral stationary phases were applied in open tubu lar gas chromatography and SFC and in micro-liquid chromatography. (C) 1996 John Wiley & Sons, Inc.
