      J. Planar Chromatogr. 30, 440-452 (2017). For electroseparation experiments in a commercially available, open-air electrophoresis box, thirteen types of separation layers (filtrating paper, office paper, chromatography paper, Japanese paper for aircraft paper models, potato starch on cellulose support, common HPTLC glass plates coated with cellulose, silica gel, RP-18W, and aluminum oxide as well as glass-based nutrient agar layers) were investigated. The best separation was observed for the cellulose pre-coated TLC layer and the starch layer on filtrating paper support. The study revealed substantial differences between the electrophoretic migration of target dyes within cellulose type layers and also in comparison to the remaining stationary phases studied. Combined planar electrophoresis–electrochromatography of methyl red and ponceau R colorants on active thin-layers composed of starch powder on cellulose strips and agar layer on glass-based support connected with electrolyte containers. The resulting dye pattern on active layers was acquired using an office scanner.

Detection by dipping in aqueous Rhodamine B reagent (0.025 %), evaluation under UV 366 nm. Quantitative determination by fluorescence measurement at 366/>400 nm with the Hg lamp. The hRF value of oleyl oleate was 30 and of stearyl stearate 40. The mean recovery rate (104 %) was determined by analyzing salmon samples spiked to contain 20 % wax esters. The wax ester content of an escolar sample was 18-22 % (n=3). The repeatability was <5 % and the mean laboratory precision 3 %.
