J. Planar Chromatogr. 26, 358-362 (2013). HPTLC of sertraline in human serum on silica gel with toluene - ethyl acetate - methanol - glacial acetic acid 9:3:2:1. Quantitative determination by absorbance measurement at 220 nm. The hRf of sertraline was 45. Linearity was between 1 and 70 ng/zone. LOD and LOQ were 120 and 250 pg/zone. Recovery (by standard addition) was found to be 94.6-99.0 %. The % RSD values of intra- and inter-assay were between 0.9-2.8 % and 0.8-3.4 %, respectively.

J. Planar Chromatogr. 6, 413-415 (1993). TLC of nitroaromates and carbazoles (9-nitroanthracene, 1-nitronaphthalene, 2-nitrofluorene, 1-nitropyrene, carbazole, 1,2,7,8-dibenzcarbazole, 1,3-dinitropyrene, 2,7-dinitrofluorene) on silica with hexane - dichloromethane 1:1. Detection under UV 254 and 365 nm, followed by spraying with freshly prepared reducing agent (0.1 g sodium borohydride) dissolved in a mixture of 15 mL methanol, 3 mL water, and 1 mL of 0.05% copper(II)chloride solution and again observation under UV at 365 nm. Azaarenes were separated on cellulose with DMF - water 1:4. Detection by observation under UV both before and after reaction in a chamber containing trifluoroacetic acid fumes.

Biochemical systematics and ecology 16, 505-508 (1988). TLC of hydrocarbons on silica with hexane - ether - formic acid 40:10:1. Visualization under UV after spraying with a 0.2% ethanolic solution of 2',7'-dichlorofluorescein. The hydrocarbon fractions were recovered from silica by elution with chloroform - methanol and analysed by GC.

J. Planar Chromatogr. 22, 255-263 (2009). TLC of 25 triphenylmethane derivatives using paraffin oil-coated silica gel and acetone-water mixtures, in which the acetone content varied between 40 and 70 % in increments of 10 %. Dual retention behavior is observed for triphenylmethane derivatives in reversed phase HPTLC when the composition of acetone-water mobile phase is varied. The physicochemical and molecular properties of triphenylmethane derivatives lead to an unusual retention behavior, which was investigatd by traditional quantitative structure-retention relationship modeling and by 3D molecular modeling. Lipophilicity was found to be the most important molecular property governing the retention of triphenylmethane derivatives.
