摘　　要：A new β-cyclodextrin modified hyperbranched carbosilane stationary phase for gas chromatography was synthesized by substituting the -OH groups of β-cyclodextrin with hyperbranched carbosilane and was coated on the inner wall of fused silica capillary column for gas chromatography. The chromatographic behaviors of the stationary phase were studied. The initial testing results showed that it possessed good separation abilities for several kinds of mixtures, such as benzenes, acrylates, ketones and alkylchlorides.A new β-cyclodextrin modified hyperbranched carbosilane stationary phase for gas chromatography was synthesized by substituting the -OH groups of β-cyclodextrin with hyperbranched carbosilane and was coated on the inner wall of fused silica capillary column for gas chromatography.
