ABSTRACT
In capillary zone electrophoresis (CZE), cationic and anionic analytes may be separated based on differences in their charge-to-size ratio, and subsequently measured on-column by UV detection. Compared with the traditional chromatographic techniques, CZE provides an alternative separation principle characterized by high separation efficiency, rapid separations, and by a low consumption of reagents as well as solvents. Based on these advantages, CZE has been implemented in a broad of applications areas including pharmaceuticals, proteins, peptides, agrochemicals, raw materials, water, DNA, surfactants and fine chemicals [1]. Today, CZE is one of the most promising separation techniques in bio-analysis [2-5], food control and safety [6, 7], and even environmental applications [5, 8], where low analyte concentrations are expected. In this chapter, examples of some CZE environmental applications will be presented and discussed.
