J.A.O.A.C. 69, 641-643 (1986). TLC of sulfathiazole residue on silica with pentanol - chloroform 9:1. Detection by spraying with fluorescamine. Quantification by densitometry using sulfaquinoxaline as internal standard. Detection limit 0.02 mg/kg. Calibration curve was found linear 0.05- 0.60 mg/kg; recovery 98 %; 50-60 samples per day can be done by a single analyst.

J. Planar Chromatogr. 11, 844-847 (1998). TLC of monensin on silica gel with ethyl acetate - dichloromethane - NH3 34:6:1. Visualization by spraying with vanillin and heating at 120°C for 1-5 min. Positive results are confirmed by spraying with p-anisaldehyde and heating at 120°C for 1-5 min.

J. Planar Chromatogr. 23, 332-334 (2010). TLC of fenvalerate, cypermethrin, and deltamethrin (as standards and extracted from minced visceral tissue) on silica gel with petroleum ether - diethyl ether 9:1 in a previously saturated TLC chamber. Detection by spraying successively with 10 % sodium hydroxide and then with 0.2 % p-benzoquinone in dimethyl sulfoxide. The LOD were approximately 0.25, 0.5, and 0.25 µg/zone for cypermethin, fenvalerate, and deltamethrin, respectively. Organochloro, organophosphorus, carbamate insecticides and pyrethroid insecticides without a cyanide group do not interfere.

J. Chromatogr. 396, 399-403 (1987). TLC on silica with toluene. Detection by the yellow-orange color of the compounds. Detection limit 0.1 µg.

Chinese J. Chem. Anal. (Lihua Jianyan, Huaxue Fence) 26, 371, 372 (1990). TLC of 4-hydroxy-3-(1-tetrahydronaphthalenyl)-coumarin (a raticide) on silica with chloroform - methanol 99:1.

J. AOAC Int. 82, 25-30 (1999). Validation of video densitometric and classical slit-scanning determinations of pesticides on TLC plates for linearity, precision, and detection limit. A comparison of results showed that slit-scanning is more sensitive and more precise than video densitometry. According to validation requirements the relative standard deviation of 3.5 - 5.3% for video densitometry is, however, acceptable . Linearities are considered as very good and almost identical for both techniques. The main advantage of video technology is the speed of a few seconds compared with 20 min with scanning densitometry; it provides excellent archiving facility, and image and chromatographic data can be stored together, edited, and used for many tasks. TLC of propham, chlorpropham, tetramethrin, a-cypermethrin, diflubenzuron, atrazine on silica gel with methanol - water 4:1.

J. Agric. Food Chem. 32, 258-262 (1984). TLC of deltamethrin and metabolites (3-(2,2-dibromvinyl)-2,2-dimethyl cyclopropan carbonic acid, 3-phenoxy benzaldehyde, 3-phenoxy benzoic acid, 3-phenoxy benzylalcohol) on silica with a) chloroform - acetic acid 99:1, b) toluene - hexane 8:2. Detection by UV 254 nm.

J. Agric. Food Chem. 33, 844-848 (1985). TLC purification of toxicant A (a variable mixture of two octachlorobornane components) on silica, developed 4 times with heptane in a saturated chamber against standards.
