      J. of Chromatogr. A 1218 (19), 2668-2675 (2011). Use of the changes in emission of berberine cation, induced by non-covalent interactions with lipids on silica gel for detection and quantification of lipids using fluorescence densitometry in HPTLC/AMD. Three different HPTLC/AMD gradients were developed for the separation of 1) neutral lipid families and steryl glycosides, 2) different sphingolipids, and 3) sphingosine–sphinganine mixtures. Rationalization of fluorescent molar responses of studied lipids, and differences in response among different lipid families in the light of a previously proposed model of FDIC response, which is based on ion-induced dipole interactions between the fluorophore and the analyte, likewise, application of computational calculations using molecular mechanics as a complementary useful tool to explain high FDIC responses of cholesteryl and steryl-derivatives, and moderate responses of sphingolipids. Proposal of an explanation for the high FDIC response of cholesterol, whose limit of detection is 5 ng.

      J. Planar Chromatogr. 17, 290-296 (2004). Description of a new AMD instrument. Its main advantages are very low cost both of construction and in use. In comparison with ascending development in conventional instruments, a laboratory-made horizontal sandwich chamber is used for development. With the help of a series of special accessories no obvious mobile phase remains in the distributor after each step thus saving a large amount of solvent. All the components of the instrument are easy to obtain, so the average worker in the laboratory could construct all the instrument except the control unit. An application of the instrument is described; the results obtained were satisfactory. Compared with the commercial instrument the main differences are 1) a horizontal sandwich chamber with funnel distributor is used as development chamber, 2) the most expensive component, a motor-driven valve, is omitted, 3) a micro air pump (normally used to supply oxygen for goldfish) is used to deliver mobile phase to the chamber. AMD separation of 13 dyes with first acetone - ethyl acetate 1:1 to compress the spots to slim bands, then seven steps with ethyl acetate - chloroform 4:21 to1:9 were completed; then seven steps with chloroform - cyclohexane 17:3 to 67:33. After these fifteen steps of AMD the mixture was separated into eighteen visible spots.
