J. Agric. Food Chem. 47, 327-332 (1999). TLC of imidacloprid, i-nitrosimine, i-olefin, and 6-chloronicotinic acid on silica gel with acetonitrile - dichloromethane 1:1 and acetonitrile - ethyl acetate - water 70:23:7. Also determination of radiochemical purity by TLC.

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.

A new approach in forensic analysis. J. Planar Chromatogr. 24, 108-112 (2011). HPTLC of ditalimfos, edifenfos, and tolclofos-methyl on silica gel, prewashed with methanol, with n-hexane - acetone 9:1 in a twin-trough chamber with saturation. Quantitative determination by densitometry in absorbance mode at 254 nm, the wavelength of maximum absorption for all three fungicides. The hRf values of all three organophosphorus fungicides increased with increasing contents of acetone in the mobile phase.

Pharmazie 42, 356 (1987). TLC of Rotenoids (terphrosin, sumatrol, rotenone, deguelin, dehydro-deguelin) on silica with chloroform - ether 95:5 or with chloroform - ethyl acetate - acetic acid 196:3:1. Vizualisation by spraying with hydroiodic reagent and heating at 120°C for 20 min.

J. Planar Chromatogr. 4, 106-110 (1991). Presentation of 3 examples of optimization of AMD gradients: 1 + 2: Universal gradients optimized for the separation of phenolic compounds spanning a wide polarity range on diol layers, 3: Optimization for the separation of organochlorine pesticides on silica spanning a low polarity range. Preliminary isocratic developments of selected standards were performed with binary solvent mixtures in order to set up the gradients. The retention data (as plots of Rm values against solvent composition) can be used for the choice of the gradient components and gradient boundaries.
