J. Planar Chromatogr. 21, 161-166 (2008). TLC of 13 newly synthesized potential herbicides (N-aryltrichloroacetamides or 2-(chlorophenoxy)acyl derivatives) on silica gel or RP-18 in saturated sandwich chambers at 20 °C with hexane - 1,2-dichloroethane 2:3. Detection in UV light at 254 nm. The lipophilicity of the substances was described by retention factors in water, log k w, both calculated from experimental RP-TLC data, and by log P values calculated by use of software. Biological activity was determined with the BioArena system. Antibacterial action against Pseudomonas savastanoi pv. phaseolicola bacterial cells and the role of formaldehyde were investigated. Additionally the effect of formaldehyde capturers (L -arginine and reduced glutathione) and Cu 2+ ions was evaluated in regard of bioactivity and toxicity. Formaldehyde and its reaction products are crucial in the action mechanism of these substances.

J. Chromatogr. 545, 214-218 (1991). Gradient multiple HPTLC (AMD) of organochlorine pesticides on silica with AMD gradient based on dichloromethane - heptane. Detection by immersion in 0.5% ethanolic solution of silver nitrate containing 5% concentrated NH3 solution, or 0.1% acetone solution of 3,5,3',5'-tetramethylbenzidine, and by irradiating under UV 254 nm for 30 min, and then scanning at 550 nm.

J. Planar Chromatogr. 22, 77-82 (2009). Detection of carbamates (carbaryl, propoxur, and carbosulfan) on silica gel activated at 110 °C for 5 min in the oven. After application the pesticide solutions were hydrolyzed by addition of 2 µL of 2 M sodium hydroxide solution. After 5 min, 5 µL diazotized p-aminoacetanilid was applied onto the spots to form the colored derivatives - red, yellow, and yellow-orange for carbaryl, propoxur, and carbosulfan, respectively. The plates were then placed horizontally in an oven at 110 °C and the colored derivatives migrated as concentric rings under the influence of the temperature gradient.

J.A.O.A.C. 71, 957-961 (1988). Two-dimensional TLC of aflatoxin B1, B2, G1, G2 on silica with diethyl ether - methanol - water 94:4.5:1.5 and chloroform - acetone 9:1. Detection under UV.

J. Chromatogr. B 704, 361-373 (1998). HPTLC on silica gel with 1) hexane - acetone 4:1, 2) toluene and on RP-18 silica gel with methanol - water 7:3. Detection under UV 254 nm and by spraying with 2% 4-(4-nitrobenzyl)pyridine in acetone and heating at 110°C for 5 min, or with 5% PdCl2 in 10% HCl. Measurement of Rf values. Investigation of the detection limits for some insecticides.

J. Chromatogr. 365, 309-314 (1986). Study of the selectivity and sensitivity of some TLC detection systems for visualization of organochlorine and organophosphorus insecticides and thiocarbamate herbicides, and quantification by densitometry. Investigated: silvernitrate-2-phenoxyethanol, 4-(4'-nitrobenzyl) pyridine, 2,6-dibromobenzo-quinone-N-chloroimine and its analogues.
