title: Separation of enantiomers using vancomycin in a countercurrent process by suppression of electroosmosis.
abstract: Excellent separations were achieved using a coated column to suppress electroosmotic flow and employing a countercurrent process between chiral selector and racemic solute. Using the macrocyclic antibiotic vancomycin as a chiral selector in capillary electrophoresis the resolution of nonsteroidal anti inflammatories and dansyl amino acids was achieved. Improvement in sensitivity due to the elimination of background absorbance and increased efficiency due to the removal of wall adsorption effects are both achieved using this technique.
