Notes:
Summary Planar electrochromatographic separations of test substances were performed on non pre-wetted, commercially available, thin-layer plates. The behavior of different layers and solvents was studied in an applied electric field of up to 2000 V cm−1. Evident electrokinetic effects, electroosmosis and electrophoresis were observed only on silica gel and polyamide layers developed with polar solvents. The selectivity of separation of nonionic and ionogenic compounds was greatly enhanced. Although experimental conditions were controlled to a certain extent, results obtained with the same solvents were reproducible within 5%.
