Abstract

Planar electrochromatography is a technique in which mixture components are separated in adsorbent layer of a chromatographic plate placed in electric field In such separation system a mobile phase movement stems from electroosmosis phenomenon Partition and electrophoresis mechanisms are involved in separation of mixture components with this technique Two principal modes of planar electrochromatography are described planar electrochromatography in an open system PEC and planar electrochromatography in a closed system pressurized planar electrochromatography PPEC The development of both modes is presented beginning with the first paper on electrochromatography by Pretorius et al in 1974 and finishing with the last papers by Dzido et al in 2010 Constructional development of equipment to planar electrochromatography is provided and influence of operating variables on separation efficiency as well The advantages and challenges of PPEC technique are especially discussed
