Theory of capillary electrochromatograpy

The present state of the theory of capillary electrochromatography (CEC) is reviewed. Emphasis is placed on electroosmosis and the electrical double l ayer, and the generally good understanding of the factors affecting the ele ctroosmotic flow in CEC columns. The relation of CEC to other electrically driven separations are described, along with band broadening, and the influ ence of column temperature in CEC. The thoretical potential of CEC is asses sed from the standpoint of current and future column technology, and likely future application areas are described.
