Chinese J. Chromatogr. (Sepu) 13, 99-103 (1995). A review with 61 references on the classification of solvents, the application of solvent strength parameters, and nine methods for the optimization of solvent systems in TLC.

Chinese J. Chromatogr. (Sepu) 15, 263-265 (1997). Presentation of a complex method for the optimization of the solvent system of cortical hormone, sulfa drugs, ginkgo biloba. Computation of the composition of the solvent system by using a proposed regression equation and a group of experimental data. Comparison of the results obtained with those obtained by verifying test, giving good agreement.

J. Planar Chromatogr. 14, 208-210 (2001). Separation of dyes, polycyclic hydrocarbons (phenanthrene, benzopyrene, anthracene, fluoranthene, pyrene, triphenylene, azulene, naphthacene, chrysene, perylene) and a vegetable chlorophyll extract on plates prepared from Piresorb A, silica gel, luminophore and liquid glass as binder with benzene, hexane, benzene - hexane 1:4 and ethyl acetate - acetonitrile 3:7. For flow TLC it is necessary to use TLC plates with sorbents different from those used in classical TLC.

J. Planar Chromatogr. 16, 402-404 (2003). Description of a new distributor which can be used more perfectly for 'half-way development' consisting of two microscope slides which are specially treated and glued together like a funnel. Mixtures of dyes have been used to verify this supposition, with satisfactory results. TLC of 5 dyes on silica gel (400 mm x 55 mm plates) with cyclohexane - ethyl acetate 3: 1 and cyclohexane - ether 3:1.

CBS 95, 10-13 (2005). HPTLC of five sulfonamides on silica gel with dichloroethane - methanol - 2-propanol - ammonia 25:5:5:1 in the twin trough chamber and ADC 2 with varied chamber saturation. Densitometric evaluation by absorbance measurement at 254 nm. Comparison of chamber saturation in conventional twin trough chamber and Automatic Development Chamber ADC 2 respectively. Reproducibility of Rf-values is better in ADC 2 due to higher quality in chamber saturation and less manual operations.

J. Liq. Chromatogr. Relat. Technol. 30, 2171-2184 (2007) Modification of a commercially available printer for application of reagents in planar chromatography and investigation of optimal settings of the printer regarding utmost reagent transfer. Evaluation of the efficacy of printing. HPTLC of taurin in energy drinks on silica gel (prewashed with methanol) with ethanol - water 3:2 in a twin trough chamber. For post-chromatographic derivatization the cartridge of a commercially available printer was filled with a modified ninhydrin solution which was printed onto the layer, followed by heating at 100 °C for 2 min. Quantitative determination by absorbance measurement at 525 nm. The results obtained for analysis of an energy drink were as good as such obtained by derivatization by dipping.

J. Planar Chromatogr. 30, 216-218 (2017). HPTLC of monocrotophos on silica gel with n-hexane – acetone 4:1. Detection by spraying with freshly prepared sodium nitroprusside reagent (1 % sodium nitroprusside in 2 N sodium hydroxide). The hRF value for monocrotophos was 80.

J. Chromatogr. 358, 288-290 (1986). Description of the preparation of a spray reagent for TLC detection of aminophenols and related compounds by mixing a 5 % aqueous solution of ZnCl2 with an equal volume of 5% aqueous K3Fe(CN)6. Detection limit 2-5 mg.
