摘要：
A method for the separation of inorganic anions by capillary zone electrophoresis is presented and applied to the determination of chloride, nitrite, nitrate, and sulfate in rain water samples. Direct injection of samples without addition of buffer leads to a significant increase of sensitivity due to solvent stacking, but the calibration curves are non-linear and display a poor reproducibility. Using chlorate as internal standard, linear calibration curves are obtained with an accuracy of better than 10%.
