Abstract
A capillary electrophoretic procedure has been developed for quantitative determination of anions in waters. This training session can be completed in 4 hours by undergraduate students. It exemplifies a separation technique, including identification of the various analytes (sulfate, chloride, nitrate) and trace analysis problems in real water samples (river water, drinking water) at the ppm level.
