Abstract
A new alkylated and silylated β cyclodextrin derivative was prepared with trimethyl chlorosilane and bromopentane. Three fused silica capillary columns were coated with the derivative by superdynamic coating method. Chromatgraphic characteristics such as column efficiency, thermal stability, polarity and column life span were studied. A series of enantiomers was separated on the three columns.
