J. Liquid Chromatogr. 12, 3135-3149 (1989). Evaluation of the luminescence detectability of several SBD-thiol derivatives on five different HPTLC layers: cellulose, C-18 silica and silica 40, 60 and 100. Influence of the type of stationary phases dipped with fluorescence enhancers. Discussion of the reasons for the phenomena. Consideration of the time elapsed between plate dipping and measurement as well as the dynamic linearity of the enhancement process. Fluorescence enhancers: Triton X-100 and liquid paraffin.

Thin-layer chromatographic differentiation of nitrones, nitroxide radicals and nitroso amines in mixtures. J. Chromatogr. 663, 127-131 (1994). TLC of title compounds on silica with chloroform (or methanol) - acetone 4:1. Detection by spraying with sodium iodide and subsequently with trifluoroacetic anhydride-sodium iodide reagent. Brown spots appear on white background, stable for more than 20 min.

J. Chromatogr. A, 740, 99-107 (1996). TLC on silica with 1) toluene - ethyl formiate - formic acid 5:4:1, and 2) ethyl acetate - formic acid - water 20:2:1. Detection by dipping into diphenylboric acid 2-aminoethyl ester solution, and by fluorodensitometry. Investigation of the effect of different substances on the intensity and stability of the fluorescence. Comments on the procedure for measurement, and discussion of the correlation between fluorescence and molecular structure.

J. Planar Chromatogr. 14, 210-212 (2001). HPTLC of monocrotophos and other organophosphorus insecticides (malathion, ethyl parathion, methylparathion, fenitrothion fenthion, phorate, dimethoate, phosphamidon, dichlorvos), organochlorine insecticides, carbamate insecticides, pyrethroid insecticides on silica gel in a pre-saturated chamber with chloroform - acetone 7:3. After drying the plate is sprayed with a 20% anhydrous sodium carbonate solution then with 0.5% chloranil (in acetone) reagent. The reagent is selective for monocrotophos among other insecticides.

J. Chromatogr. A 1182 (2), 219-225 (2008). UV imaging of spots on TLC plates while still wet with solvent. Imaging of spots of benzophenone during and after development by using a charge-coupled device camera. The limit of detection was 5 ng on a wetted plate and 3 ng on a dry plate. The relationship between peak area and sample loading was linear in the low nanogram range over an order of magnitude for both wet and dry modes. It was shown that UV measurements on wet glass plates suffer from low sensitivity; however, increased sensitivity was achieved by using aluminium plates. The separation process can be monitored by measurement of UV absorbance during TLC development on aluminium-backed plates.

J. Liq. Chromatogr. Relat. Technol. 39, 242-248 (2016). Review of the application of multivariate TLC retention data, the theory of hierarchical cluster analysis, principal component analysis and parallel factor analysis. Different applications such as exploring retention, lipophilicity analysis, quantitative structure–activity relationship modeling, solvent selection and comparison with other techniques were described.

J.Liquid Chromatogr. 8, 2875-2926 (1985). Discussion of optimization of instrumental parameters that influence resolution and signal-to-noise ratios in the recording of thin-layer chroMatograms by scanning densitometry. Proposition of a standardized method of determining sensitivity and detectability (used to evaluate the performance of a Shimadzu CS-910 scanning densitometer). Discussion of fluorescence enhancement reagents as a method of improving sample detectability in fluorescence mode as well as influence of the sorbent on position and intensity of the fluorescence emission signal.

Anal. Biochem. 171, 248-255 (1988). TLC of lipids on silica with methanol - ethanol - chloroform - NH3 1:49:6:6 or chloroform - methanol - acetic acid - water 60:45:5:3. Visualization by exposing to iodine vapor, by spraying with ninhydrin or molybdate. Chromatograms photocopied on transparent sheets, which are quantified by densitometry.
