Anal. Letters 18, (A6) 719-728 (1985). Study of the effect of commonly occurring salts in soil, organic matter and pH levels of the soil leachates on the movement of some water soluble phenols by TLC.

J. Chromatogr. A 754, 125-135 (1996). A review with 125 references on the state of the art of the individual steps (extraction, clean-up, separation, identification, quantification) of TLC as well as GC, HPLC. Discussion of the new approaches with respect to their relevancy to the requirements for increasing the sensitivity of detection and reliability of identification and quantification at low levels of concentration.

Science & Culture Jan.-Feb., 22-30 (2008). Isolation and identification of some unique chemical compounds is reported using chemical, chromatographic and spectroscopic methods such as GC-MS, HPTLC and HPLC. The presence of bio-organic molecules such as oxygenated dibenzo-a-pyrones (DBPs), their amino acyl conjugates (DCPs) and polyphenyl benzoquinones (PBQs) was observed in all the four samples of meteorites. HPTLC on silica gel with 1) n-butanol - acetone - acetic acid - water 7:7:2:4 for amino acids, detection with ninhydrine reagent and absorbance measurement at 610 nm; 2) n-butanol - acetic acid - water 3:1:2 for sugars, detection with p-anisidine reagent and absorbance measurement at 380 nm; 3) chloroform - methanol 9:1 for DBPs and absorbance measurement at 240 nm and 360 nm.

CBS 99, 14-15 (2007). HPTLC of acrylamide prechromatographically derivatized with dansulfinic acid on silica gel in a twin-trough chamber with ethyl acetate over 70 mm after focussing with methanol. Detection by dipping in a 25 % solution of propylene glycol in n-hexane. Quantitative determination by fluorescence measurement at 366/>400 nm. Precision (RSD, n=3 at 3 different concentration levels each) was 4.8 % and recovery (by standard addition) was 96 %. Linearity was between 0.1 and 0.4 µg/L. The limit of quantification was 0.08 µg/L acrylamide in drinking water. Comparison with HPLC-MS/MS showed comparable results for acrylamide in ground water.

TLC of pyrene, fluoranthene, 1,2-benzanthracene, 3,4-benzofluoranthene, 10,11-benzofluoranthene, 11,12-benzofluoranthene, perylene, 1,12-benzoperylene on silica with cyclohexane - benzene 4:1 and on cellulose with 1) hexane - benzene 9:1, 2) methanol - ether - water 4:4:1. Detection by UV 254 and 366 nm.

Anal. Chem. 67, 620-630 (1995). HPTLC of 265 pesticides on silica using AMD with an universal gradient based on dichloromethane. Compilation of the data for migration distances, the UV spectra, and the instrumental detection limits. Confirmation of suspect positive ones by a second analysis applying special gradients optimized for the classes. The pesticides were concentrated by solid phase extraction of 1 L drinking water.

J. Chromatogr. A 1116 (1-2), 272-276 (2006). Application of TLC to fractionate well-characterized aquatic humic materials coupled with the novel evaluation of the trihalomethane formation potential of the fractionated materials. HPTLC on silica gel with methanol - ethyl acetate 2:1. Identification of three common fractions based on retention factor (Rf) in all substances examined.

J. Agric. Food Chem. 50, 4619-4627 (2002). TLC on silica gel of alachlor with n-hexane - ethyl acetate 1:1, of chlorpyrifos with n-hexane - toluene 7:3, of deltamethrin with toluene - cyclohexane 7:3, of endosulfan and endosulfan-sulfate with n-hexane - acetone 9:1, of monocrotophos with acetonitrile - water 3:2, of simazine with n-hexane - acetone 1:1, of triflurolin with n-hexane - acetone 3:1. The spatial distribution of radioactivity on the TLC-plates was measured and integrated by an Instant Image Analyzer.
