title: Selected applications of cyclodextrin selectors in capillary electrophoresis.
abstract: Through the use of alpha-, beta-, gamma- and heptakis(2,6-di-O-methyl)-beta-cyclodextrin as stereospecific selectors or electrolyte modifiers, both in capillary zone electrophoresis and isotachophoresis, selected model isomeric compounds (including optical isomers) were resolved. Soluble alkylhydroxyalkylcellulose derivatives were further added to the cyclodextrin-modified background electrolytes under study. Their presence was found to be essential, as demonstrated by improvements in both enantioselectivity and separation efficiency. The results obtained in both electrophoretic modes, under optimized conditions, are compared and discussed.
