Capillary zone electrophoresis was employed for the determination of pyridoxine using end-column amperometric detection with a carbon ยฎber microelectrode at a constant potential of 0.72 V (vs. SCE). The optimum conditions of separation and detection are 1.0610 72 mol/L NH 4 Clยฑ1.0610 72 mol/L NH 3 f
