Abstract
The determination of the concentration of inorganic anions can be accomplished by using capillary zone electrophoresis (CZE). Since this is a fairly new analytical technique showing tremendous promise, it should be introduced to students at the undergraduate level. Herein, we describe a CZE experiment developed for instrumental analysis chemistry laboratory that can be modified for other species or substances.
