title: Enantiomer separation using mobile and immobile cyclodextrin derivatives with electromigration.
abstract: The principle of electrochromatography is applied to enantiomer separation with wall-coated capillaries of 50 microns (ID). As chiral stationary phase an immobilized polysiloxane containing chemically bonded monokis-6-O-octamethylene-permethyl-cyclodextrin (beta- or gamma-Chirasil-Dex) was used. The results are compared with the conventional method of adding cyclodextrin derivatives as chiral pseudostationary phase to the running buffer.
