For the first time, planar electrochromatography in an open system was introduced to the scientific literature in 1974 [1], and in a closed system in 2004 [2]. The latter technique was called pressurized planar electrochromatography (PPEC). Inspired by the results of the papers mentioned, our team also conducted research in this area. In this presentation, we provide a retrospective review of developments in pressurized planar electrochromatography and present the latest research that documents further progress in this separation technique, and two other techniques, which have been evolving because of investigations based on the former:
- pressurized planar electrochromatography, in which the flow of the mobile phase is generated by the action of an electric field (electroosmotic effect);
- orthogonal pressurized planar electrochromatography, in which the flow of the mobile phase is hydrodynamic, and an electric field is applied perpendicular to the direction of this flow;
- high-pressure layer electrochromatography, in which the flow of the mobile phase is hydrodynamic, and the electric field is applied parallel to the direction of this flow.
We also discuss the advantages and problems that should be the subject of further research on the techniques presented.
