J. Chromatogr. 351, 383-387 (1986). TLC on silica with chloroform - methanol 9:1. Detection by spraying with 0.5 % p-chloranil in dioxane followed by DMF, or 0.5 % p-fluoranil in dioxane, or 0.5 % 2,5-dichloro-p-benzo-quinone in dioxane, followed by DMF or by 0.5 % 2,5-dichloro-p-benzoquinone in DMSO. Detection limit 0.5-4.0 mg.

J. Chromatogr. 437, 131- 137 (1988). Investigation of the effect of the temperature of a liquid crystal detector and the conditions of mapping TL chromatograms of limited detectability. Discussion of the optimum parameters and the possibility of applying the liquid crystal method to quantification.

J. Indian Acad. Forensic Sci. 29 (2), 3-8 (1990). A simple, sensitive and specific color reaction for the detection of carbaryl (detection limit 1µg) based on the condensation of ß-naphthol (product of carbaryl hydrolysis) followed by oxidation is described. Since other carbamate insecticides do not give the same red-violet color reaction it can be used routinely for specific detection in biological materials in forensic toxicology.

Analyst 119, 2761-2764 (1994). Description of a novel approach for the screening of title compounds by using matrix solid phase dispersion, a microcolumn preconcentration and TLC detection on silica with ethyl acetate. Visualization by spraying with fluorescamine solution and under UV 366 nm. Detection limit 100 ppb. Presentation also of the results from the industrial evaluation of the complete method.

Anal. Biochem. 269, 410-417 (1999). Quantitative analysis of glutathione (GSH) or of glutathione S-Transferase (GST) activity using a new fluorescent molecule, 5-(pentaflourobenzoylamino)fluorescein (PFB-F). TLC of the formed glutathione adduct, GS-TFB-F, and of excess PFB-F on silica gel 60F254 with 1-butanol - methanol - water 3:1:1. The GS-TFB-F adduct spots were quantified with a fluorescence plate scanner using the blue fluorescence/chemifluorescence (480 nm) mode. Detection limits for GSH and for GST activity were 10 pmol/(l and 1 ng/(l, respectively.

J. Planar Chromatogr. 18, 141-146 (2005). TLC of fatty acids (ethanoic, propanoic, butanoic, pentanoic, hexanoic, heptanoic, and octanoic acid) on silica gel with hexane - acetone 4:1 or acetone - water - chloroform - ethanol - aqueous ammonia 30:1:3:5:11 with chamber saturation for 30 min. Only bromocresol green, bromophenol blue, potassium permanganate, and methyl red can be used for the detection. Among the new visualizing agents dipping of the plates in an aqueous solution of alkaline blue enables the detection of the free fatty acids from propanoic to octanoic. Dipping generated better contrast regarding the spots than spraying.

Phytochem. Anal. 24, 303-308 (2013). HPTLC of chicoric acid (1), chlorogenic acid (2) and echinacoside (3) in commercial Echinacea products on silica gel with ethyl acetate - formic acid - acetic acid - water 100:11:11:17. Qualitative identification under UV 366 nm. Images were quantified and transformed into chromatograms, as signal intensities (peaks) versus hRf (retention factor) for a artificial neural network (ANN) correlation. LOD were 19, 46 and 29 ng/band, whereas LOQ were 63, 154 and 98 ng/band for (1), (2) and (3), respectively.

HPTLC, Wuerzburg" IfC, Bad Duerkheim 1985, 373-380.Description of the method,, which can be used for detection, identification and quantification in both absorbance and fluorescence. Application example from drug analysis (anthraquinone type, laxative).
