A liquid crystal stationary phase for open tubular capillary electrochromatograpy (OTCEC) is fabricated by etching a fused silica tube and then bonding 4,4′-cyanopentoxy biphenyl by a silanization/hydrosilation process. The versatility of this electrophoretic capillary is demonstrated by separations of proteins, peptides, basic pharmaceuticals and the metabolites of tryptophan. Chromatographic interactions...
