Capillary Column Coated with Heptakis(2,3, 6-tri-O-octyl)-β-cyclodextrin Using Sol-gel Technology

摘要

Heptakis(2,3,6-tri-O-octyl)-β-cyclodextrin was coated onto the fused silica capillary by sol-gel technology.Column efficiency and column selectivity were studied.The results indicated that high ability of separation was acquired.Positional isomers of aromatic compounds were well separated.
