Electric fields have been shown to affect peak width, peak area, and other chromatographic properties in reversed-phase TLC on silanized silica gel and RP-18. To eliminate electroosmotic flow, thin layer electro-chromatography was performed on unwetted layers. Different modes of thin-layer electrochromatography - horizontal and vertical - were investi-gated, but only for chromatographic systems in which van der Waals forces are the sole interactions - the solutes chromatographed were polycyclic aromatic hydrocarbons and hexane or heptane were used as mobile phases. On the basis of the data obtained has been shown that the electric field affects the chromatographic process not only by replacing capillary flow by electroosmotic flow.
