J. Planar Chromatogr. 16, 263-267 (2003). Comparison of selectivities of TLC systems by use of correlations between RF(II) and RF(I) values (by analogy with two-dimensional TLC). 2D-TLC of 10 urea herbicides (monolinuron, linuron, metobromuron, chlorbromuron, chlorotoluron, diuron, metoxuron, isoproturon, chloroxuron, methabenzthiazuron) on cyanopropyl-modified silica gel, normal-phase with ethyl acetate - heptane 1:4 (step A) and reversed-phase with dioxane - water 2:3 (step B). Also separation by the 2D-TLC system comprising normal-phase chromatography on silica gel with tetrahydrofuran - heptane 2:3 and reversed-phase on RP-18 silica with methanol - water 3:2. Detection under UV 254 nm. One-dimensional HPTLC on RP-18 and cyanopropyl-modified silica gel.

J. Liq. Chromatogr. Relat. Technol. 33, 880-893 (2010). TLC of 6 carboxamide fungicides and 11 phenylbenzamide derivatives on silica gel and aluminium oxide impregnated by overnight predevelopment in n-hexane - paraffin oil 19:1 with mixtures of methanol - water, acetonitrile - water, tetrahydrofurane - water, and acetone - water with the concentration of organic modifier varying in steps of 5 %. Detection under UV light. The RMO and b values related to the molecular lipophilicity and to the specific hydrophobic surface area (b) of the solutes were calculated separately for each RP-TLC system and for each analyte. The correlations between the physicochemical parameters measured were calculated by linear regression analysis.

J. Planar Chromatogr. 8, 194-199 (1995). TLC of TMTD (thiram, tetramethyl dithiocarbamoyl disulfide), thiophanate-methyl and 3-indolebutyric acid on silica with hexane - ethyl acetate - acetone 4:4:1. Quantification by densitometry at 254 nm using either p-hydroxyacetanilide or propiophenone as internal standard.

J. Planar Chromatogr. 17, 192-199 (2004). TLC of 3-ethyloxycarbonyl-5-substituted-2,4-dioxotetrahydro-1,3-thiazole derivatives (2’-fluoro-6’-chlorobenzylidene, 1’-naphthylidene, 4’-methoxybenzylidene, 2’-oxybenzylidene, 2’-thienylidene, 4’-dimethylaminobenzylidene, 1’-carboethoxy-3’-indolylidene, 3’,4’-dimethoxybenzylidene, 4’-isopropylbenzylidene, benzylidene) on silica gel with non-polar diluent (hexane) - polar modifier (ethyl acetate, acetone, or dioxane) and on reversed-phase systems of the type rice starch with polar diluent (aqueous ammonia) - polar modifier (methanol, acetone, or dioxane). Examination of the dried plates after development under UV light at 254 nm.
