J. Planar Chromatogr. 10, 124-127 (1997). Development of a new color reaction based on the formation of black lead sulfide by treatment of mancozeb with alkaline plumbite solution. TLC of mancozeb on silica gel cellulose, calcium sulfate, titanium oxide, soil, etc. Detection limit 0.45 µg/spot. Fungicides other than dithiocarbamates do not interfere.

J. Liq. Chromatogr. Relat. Technol. 33, 980-995 (2010). HPTLC of bronopol and Kathon CG on silica gel (pre-washed with methanol) with methanol - dichloromethane - n-hexane 2:12:7. For detection, luminescent Vibrio fischeri bacteria were cultivated. Plates were dried for 30-40 min at 120 °C on a plate heater and then immersed for 1 s in the bacteria suspension using an immersion device and a glass dip tank. Excess bacteria suspension was removed. Images were taken using the BioLuminizer with an exposure time of 55 s. The effective and reasonably fast quantitative method is in routine use at several laboratories.

J.A.O.A.C. 69, 646-651 (1986). TLC purification of N-methyl- and N-ethyl-1,3-propanediamine -bis-2-nitro-4-trifluoromethylphenyl derivatives on silica with toluene - ethyl acetate 85:15. Detection by UV 254 nm.

J. Agric. Food Chem. 39, 977-980 (1991). TLC of koninginin B and dihydrokoninginin B on silica with toluene - ethyl acetate - formic acid 5:4:1, visualization with UV 254/366 nm or by spraying with anisaldehyde and heating.

J. Anal. Toxicol. 19, 576-580 (1995). HPTLC of anticoagulant rodenticides ( brodifacoum, bromadiolone, chlorophacinone, coumatetralyl, coumachlor, difethialone, difenacoum, warfarin) on RP-18 with methanol - 4.72 M phosphoric acid 9:1. Quantification by densitometry at 286 nm. Detection limit 0.2 µg/mL.

CBS 114, 13-15 (2015). To test the new HTpSPE–TOFMS screening, TLC of a pesticide mixture (acetamiprid, azoxystrobin, chlorpyrifos, fenarimol, mepanipyrim, penconazole, pirimicarb) in several plant matrices (cucumber, tomato, grape, apple extracts) on amino layer pre-treated by dipping in 2 % formic acid solution in acetonitrile and drying for 10 min. Development with 10 mL acetonitrile, migration distance 75 mm, drying 5 min; second development in the backwards direction with 10 mL acetone, migration distance 45 mm, drying 3 min. Detection under UV 254 nm, UV 366 nm and white light. For HTpSPE and μL-flow injection analysis–TOFMS the target analyte zone was eluted with the TLC–MS Interface into autosampler vials with acetonitrile – 10 mM ammonium formate 1:1, flow rate 0.2 mL/min, Elution time was 60 s. An HPLC system was coupled via a PEEK capillary and a nano-electrospray ionization interface to a TOFMS without an analytical column. The mean recovery for a pesticide mixture spiked into fruit and vegetable extracts was between 86 % and 116 % with %RSDs of 1.5–10 % (n = 5).

Acta Veterinaria 31, 189-192 (1983). TLC of T-2 toxin, diacetoxscirpenol on silica with Chloroform - ethanol 8:2. Detection by UV 365 nm.

J. Agric. Food Chem. 35, 384-387 (1987). TLC separation of 2 fluvalerate diastereomers (SR, RS and SS, OR) on silica developed 6 times with hexane - ether 20:1. Also two-dimensional TLC.
