Recent developments in capillary electrokinetic chromatography with replaceable charged pseudostationary phases or additives

Electrophoresis. 2003 Sep;24(17):2924-34. doi: 10.1002/elps.200305573.

Abstract

Although electrochromatography in packed beds or monolithic columns has gained enormous interest, techniques based on charged pseudostationary phases like micelles are of high practical importance in electrically driven separation science. However, nonmicellar alternatives, e.g., using charged soluble polymers or smaller additives are still attractive, as they allow high concentrations of organic solvents, and their application is not limited by the critical micellar concentration. This review discusses the developments in the field of electrokinetic chromatography with these additives in the last three years, covering ionic polymeric pseudostationary phases, dendrimers and so-called micelle polymers, but also small molecules which implement separation selectivity due to their specific interaction with the analytes.
