J. Planar Chromatogr. 20, 419-421 (2007). HPTLC of tricyclazole, thiram, and folpat on silica gel prewashed with methanol, with hexane - acetone 3:2 in an unsaturated twin-trough chamber. Densitometric evaluation at 235 nm. The limit of detection was 12, 30, and 40 ng/zone, for tricyclazole, thiram, and folpat respectively.

HPTLC of bifonazole in cream and lotion on silica with hexane - ethyl acetate - acetone - diethylamine 45:45:10:4. Quantification by densitometry (absorbance) by 260 nm. Precision 4,8% for 20 ng per spot, 1,9% for 40 ng per spot. Overall RSD was 4,6% for cream and 5.1% for lotion.

J. Nat. Prod. 63, 1050-1054 (2000). 2D-TLC of fungicides or of crude extract material on silica with methanol - dichloromethane 1:9 in the first dimension, and, after air drying with ethyl acetate - hexane 1:1 in the second direction. Visualization under UV 254 nm or with H2SO4 in ethanol 1:19 and heating. Spraying of the dried plates with a nutrient broth spore suspension and incubation during 4 days. Determination of the dimensions of the zones of antifungal activity.

J. Planar Chromatogr. 25, 101-107 (2012). HPTLC of mixtures of the pesticides glyphosate, acephate, chlorpyrifos, malathion/methyl parathion, and isoproturon on silica gel impregnated with 0.01 % CTAB (Ncetyl-N,N,N-trimethyl ammonium bromide) and developed with hexane - acetone 1:1. LOD of the pesticides was aproximately 20 µg/band. The method can also be applied for fast determination of pesticides in cereals, vegetables and fruit grains.

HPTLC of fenvalerate [(RS)-a-cyano-3-phenoxybenzyl(RS)-2-(4-chlorophenyl)-3-methylbutyrate] and deltamethrin [(S)-a-cyano-3-phenoxybenzyl(1R,3R)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylate] on silica gel, after prewashing with methanol, with hexane - toluene 1:1. Densitometry at 220 nm. Simple and rapid TLC procedure.

J. of Chromatogr. A 1218 (37), 6540-6547 (2011). New approach and application of highly automated planar chromatographic tools for powerful clean-up, called high-throughput planar solid phase extraction (HTpSPE), which is indispensable for preventing matrix effects in multi-residue analysis of pesticides in food by liquid and gas chromatography coupled to mass spectrometry, employing TLC to completely separate pesticides from matrix compounds and to focus them into a sharp zone, followed by extraction of the target zone by the TLC-MS interface, thus resulting in extracts nearly free of interference and free of matrix effects, as shown for seven chemically representative pesticides in four different matrices (apples, cucumbers, red grapes, tomatoes), and completion of clean-up of one sample in a manner of minutes. Regarding the clean-up step, quantification by LC–MS with mean recovery (against solvent standards) of 90–104% and relative standard deviations of 0.3–4.1% (n = 5) for two spiking levels of 0.1 and 0.5 mg/kg.
