J. Planar Chromatogr. 19, 15-20 (2006). TLC and HPTLC of fifteen urea pesticides (monolinuron, chlorotoluron, diuron, isoproturon, linuron, dimefuron, diflubenzuron, teflubenzuron, lufennuron, thifensulfuron methyl, triasulfuron, chlorsulfuron, rimsulfuron, amidosulfuron, tribenuron methyl) on RP18 with methanol - water and mixed organic (acetonitrile - methanol 1:1) - 0.1 % aqueous orthophosphoric acid mobile phases, and on silica gel with benzene - methanol and benzene - ethanol mobile phases. Relationships between Rf values and mobile phase composition were determined.

J. Liq. Chromatogr. Relat. Technol. 32, 1241-1258 (2009). HPTLC of 11 pesticides in water samples on silica gel with ethyl acetate - n-heptane 2:8, 3:7, 2:3 or 7:30. Quantitative determination by absorbance measurement between 200 to 600 nm with average optical resolution better than 2.0 nm. Linearity was between 0.1 and 17 µg/zone for all pesticides. The LOD was between 40-650 ng/zone. Results were comparable with a HPLC method.

J. Liquid Chromatogr. 6, 139-143 (1983). TLC of Carbaryl, Bendiocarb, Carbafuran, Baygon, Ziram, Zineb, Aldicarb, MIBC, BPMC on silica, impregnated with 1 % zinc acetate, with benzene - ethyl acetate 5:1. Detection with ceric sulfate in 60 % sulfuric acid or iodine vapor.

Special part: TLC of lipids, vitamins, carotenoids, flavonoids, organic acids, pesticides, insecticides, antioxidants, mycotoxins, surfactants.

J. Planar Chromatogr. 3, 15-19 (1990). HPTLC of 13 organic-nitrogen pesticides on silica with mixtures of hexane – dioxane 8:2, 6:4, 4:6 and 2:8. Optimization of mobile phase composition was carried out by using a comprehensive computer program written in HP BASIC 4 language. The separation of spots on the chromatograms showed agreement between predicted and experimental chromatograms.

Part II: Limitations. J. Planar Chromatogr. 5, 246-250 (1992). Optimization of a HPTLC method (K. Burger et al., J. Planar Chromatogr. 3, 504-510 (1990); in G. Angletti, A.A. Bjoseth, (Eds.), Organic Micropullutants in the Aquatic Environment; Kluwer Academic, Dordrecht-Boston-London (1991). Recommendations: Prewash the HPTLC plates by immersing in 2-propanol for at least 30 min; use of a thin (100 µm) HPTLC layer in order to increase the sensitivity of the UV detection by a factor of 2 to 3. Solvents of at least „chromatographic quality“. Reproducibility of migration distances ± 1 mm (both on the same plate and on different plates).

Jap. J. Toxicol. Environ. Health 40, 101-110 (1994). TLC of 46 common pesticides in serum and gastric lavage solutions on silica with 4 developing systems and 3 detection methods. Detection of 24 pesticides at < 500 ng by viewing under UV radiation, of 12 ones by spraying with Dragendorff's reagent. Study of the recoveries by using spiked serum samples.

J. Planar Chromatogr. 10, 80-89 (1997). Review for the period of 1994-1996 of advances in the applications of TLC and HPTLC for the separation, detection, and qualitative and quantitative determination of pesticides, other agrochemicals, and related compounds. Analyses are covered for a variety of samples, such as food and environmental, and for residues of pesticides of various types, including insecticides, herbicides, and fungicides, belonging to different chemical classes. A limited number of references on formulation analysis and the use of radio-TLC for studies of pesticide metabolism are also included. A collection of representative chromatographic systems for practical separations and analyses of a variety of pesticides are presented at the end of the review: 1. Introduction; 2. Materials and techniques (Sample preparation; thin layer plates, mobile phase selection, and plate development; detection and identification of zones), 3. Applications of TLC (General analytical studies and multiclass, multiresidue procedures; organochlorine (OC) and pyrethroid insecticides; organophosphorus (OP) pesticides; carbamate insecticides; herbicides and plant growth regulators; fungicides; miscellaneous pesticides, metabolites, and other compounds of agrochemical and environmental interest), 4. Hydrophobicity, metabolism, and data transfer studies, 5. Books and earlier reviews on pesticide TLC, 6. Selected chromatographic systems for the analysis of pesticides of various classes (70 references).
