Abstract A capillary zone electrophoresis method was developed for the determination of 8 arsenic and selenium species in a polymer-coated capillary. Large-volume stacking with matrix removal was used for sensitivity enhancement. The entire analysis time was only a few minutes. The experimental sensitivity enhancement for 7 species was found to be near its theoretical value. Coating capillaries for long-term stability in alkaline buffer electrolytes was also investigated.

Acetonitrile Concentration

In this paper, using capillary zone electrophoresis method determined Vitamin C content in saposhnikovia divaricata. 20 mmol/L borax solution and 20% acetonitrile concentration, 20kV voltage, 254 nm UV detection wavelength was chosen for electrophoretic analysis. Measured vitamin C content in saposhnikovia divaricata were 0.297 mg/g (RSD=5.9%) (n=7).
