Sweeping of analyte zones in electrokinetic chromatography

The sweeping phenomenon in electrokinetic chromatography under a considerab ly homogeneous electric held is theoretically examined and experimentally v erified, The roles of analyte charge, retention factor, and electroosmotic flow are given consideration. Experimental studies are performed using mice llar electrokinetic chromatography with sodium dodecyl sulfate as a micelle -forming agent. Uses and limitations of the new phenomenon are also critica lly conveyed.
