Sweeping of Analyte Zones in Electrokinetic Chromatography

Abstract

The sweeping phenomenon in electrokinetic chromatography under a considerably homogeneous electric field is theoretically examined and experimentally verified. The roles of analyte charge, retention factor, and electroosmotic flow are given consideration. Experimental studies are performed using micellar electrokinetic chromatography with sodium dodecyl sulfate as a micelle-forming agent. Uses and limitations of the new phenomenon are also critically conveyed.
