J. Chromatogr. A 1217 (23), 4868-4872 (2010). Comparison of the kinetic performance, measured by plate height, of high-performance thin-layer chromatography (HPTLC), high-performance liquid chromatography (HPLC) and pressurized planar electrochromatography (PPEC). HPTLC on RP18W with mobile phases composed of acetonitrile - buffer. The HPLC column was packed with the same adsorbent, which was scrapped from an RP18W HPTLC plate. An additional HPLC column was packed with C18-type silica based (LiChrosorb RP18) adsorbent of 5 µm particle diameter. The plate height of both HPLC and PPEC systems depends on the flow velocity and the migration distance of the mobile phase. As test solution prednisolone succinate was used. The best performance was obtained by the PPEC system. The separation efficiency of the systems was investigated and confirmed by use of a test component mixture composed of six hormones.

J. Chromatogr. 264, 154 (1983). This work demonstrates the applicability of gamma-aminopropyl silanized silica (chiral stationary phase) to the direct separation of enantiomers via TLC. TLC of racemic 2,2,2-trifluoro-1-(9-anthryl) ethanol on gamma-aminopropyl silanized silica with benzene - isopropanol 95:10. Possibility for quantitative and qualitative analysis by this method.

J. Planar Chromatogr. 4, 255-257 (1991). HPTLC of progesterone, testosterone, testosterone hydrogen sulfate sodium salt, 20ß-hydroxy-4-pregnene-3-one, 2-methoxy estrone, coprostane, hydrocortisone on silica with a gradient consisting of methanol – ethyl acetate – chloroform – methylene chloride (first inverse gradient program) and of methanol – chloroform (second inverse gradient program). Detection under UV 254 nm. Quantification by densitometry.

Trends Anal. Chem. 82, 100-108 (2016). Review on the application of microwave assisted extraction of bioactives from plant matrix. The review discussed microwave assisted extraction coupled with HPTLC as a technique for the analysis of individual phenolic antioxidants.

Chromatographia 30, 436-444 (1990). Investigation of the efficiency of diantipyrilmethane as a reagent for TLC of metals (titanium, zirconium, hafnium, rare earth elements, transition and platinum metals). Discussion of the peculiarities of the chromatographic behavior of metal diantipyrilmethanates and the mechanism of their TLC retention. Use of the method for the determination of metals based on complex formation directly in the sorbent layer or by liquid extraction. TLC on silica with organic solvent-mineral acid mixtures. Quantification by densitometry or spectrophotometry.

J. Planar Chromatogr. 24, 10-15 (2011). TLC of Sudan II, Sudan III, p-methoxyazobenzene, p-aminoazobenzene on silica gel reversed-phase sintered glass plates with numerous mobile phases. RP-phenyl sintered plates, i. e. sintered plates bonded with phenyl, were unsuitable for planar electrochromatography if the mobile phase contained no buffer salts, irrespective of whether or not the plates were end-capped. RP-18 sintered plates end-capped with an appropriate amount of phenyl were suitable for PEC and showed a similar separation ability but a higher electroosmotic flow than RP-18 sintered plates end-capped with an appropriate amount of methyl.

J. Planar Chromatogr. 29, 15-21 (2016). Planar electrochromatography of polyaromatic hydrocarbons (thiourea, naphtalene, acenaphthylene, phenanthrene-anthracene, fluoroanthene and pyrene) on silica-based monoliths functionalized with octyl groups with citrate buffer (pH 5.4) – methanol 1:29 and a voltage of 20 kV. _x000D_
