%X An insoluble beta-cyclodextrin polymer cross-linked with epichlorohydrin was prepared. beta-Cyclodextrin polymer (0.26 g) was treated for 0.5 h by a ultrasonator in the mixed solvent (10 mL) of isopropyl ether, methylene dichloride and benzene with a volume ratio 2:1:2, and a 26 g/L colloidal stationary liquid was prepared. It was coated on a fused silica capillary by superdynamic coating method. The capillary column was of high column efficiency of above 3,000/m with good thermal stability and moderate polarity. Enantiomers of xylene, dichlorobenzene, alpha-pinene, beta-pinene, ethyl lactate, alpha-phenyl ethanol, 1, 2-propanediol, alpha-lonone, methyl alpha-chloropropionate and gamma-valerolactone were separated on the capillary column. The experimental results showed that beta-cyclodextrin polymer treated by a ultrasonator is a capillary chromatographic stationary phase with good performance and high selectivity.
