J. Planar Chromatogr. 6. 319-320 (1993). TLC of nitrofurazone, nitrofurantoin, furaltadone, and furazolidone on silica (with concentration zone) with dioxane - chloroform 1:1. Detection by spraying with pyridine and immediately illuminating with UV light at 366 nm, resulting in the formation of yellow resp. yellow-green spots. Visual comparison against a standard equivalent to the maximum residue level (MRL) set by European countries ( 5 µg/kg).

J. Sliwiok (ed.): Acta Chromatographica 10, 213-221 (2000). TLC of cypermethrin, deltamethrin, and fenvalerate in wheat on hydrated zirconium oxide layers with different mobile phases. Good separations with methyl acetate - formic acid 4:1, ethanol - hexane 1:1, acetone - cyclohexane 3:2. Derivatization with iodine vapor and o-tolidine reagent. Detection limit was 1 µg (0,1 ppm).

J. Planar Chromatogr. 23, 184-189 (2010). Multidimensional planar chromatography on monolayer or multiphase plates and modern fiber optical TLC densitometer scanners with DAD is especially useful for correct identification of components of difficult, complicated mixtures, e.g. pesticides in plant extracts (after preliminary clean-up and concentration by, e. g., solid-phase extraction). TLC of clofentezine [3,6-bis(2-chlorophenyl)-1,2,4,5-tetrazine] in Herba Thymi on silica gel in a horizontal chamber with tetrahydrofuran - n-heptane 3:7 in the first direction, then with ethyl acetate - n-heptane 1:4 in the second direction. Detection in the range of 200 to 600 nm with a TLC-DAD scanner. Also TLC of thyme herb extracts on silica gel and on RP18 plates with tetrahydrofuran - n-heptane 3:7 in the first direction and with methanol - water 7:3 in the second direction. LOD and LOQ were 0.23 and 0.70 µg/band, respectively, in TLC-DAD and 0.35 and 1.06 µg/mL, respectively, in HPLC-DAD. Average recoveries from the spiked plant material samples were 80.1 % and 100.5 % at 2.5 µg/g and 95.1 % at 5 µ/g measured at 202 nm.

Anal. Chem. 318, 276-277 (1984). (Quantitative determination of thiabendazole by TLC and gas liquid chromatography.) TLC of thiabendazole on silica with ethyl acetate - MEK - formic acid - water 5:3:1:1. In situ fluorometry at 365 nm. Comparison with GLC.

J. Agric. Food Chem. 33, 988-993 (1985). One- or two- dimensional TLC of fenvalarate ((1, cyano (3-phenoxyphenyl) -methyl) 4-chloro-alpha -(1-methylethyl) benzene acetate) and metabolites on silica using hexane - acetone - acetic acid 25:25:1 and toluene - ether - acetic - acid 75:25:1; visualization via autoradiography.

J. Liquid Chrom. 10, 3623-3636 (1987). TLC of herbicides and plant growth regulators on calcium sulfate by sequential TLC with acetone, benzene, CCl4, chloroform, ethyl acetate, dioxane, propanol. Detection by spraying with 1% ethanolic alkaline bromophenyl blue solution.

TLC separation of organophosphorus and carbamate insecticides (phorate, phosphamidon, DDVP, phosalone, carbaryl, aldicarb) on silica with hexane - acetone 4:1 (after presaturation). Detection by spraying with freshly prepared spray reagent (0.1 g anhydrous zinc chloride and 0.5 g diphenylamine in 100 mL acetone) and heating at 110 °C for 10 min.

J. Chromatogr. 643, 271-290 (1993). Review with 290 references on TLC of pesticide residues in various environmental samples. Presentation of the results from numerous papers in tabular form.
