J. High Resol. Chrom. 12, 345-347 (1989). TLC separation of thiol compounds (captopril, coenzyme A, cysteamine HCl, cysteine HCl, glutathione) after derivatization with ammonium 7-flurobenzo-2-oxa-1,3-diazole-4-sulfonate (SBD-F) on HPTLC silica with isopropylether - methanol - water - acetic acid 9:8:2:1 as eluent in a twin trough chamber. Visualization under UV 366 nm, quantification by densitometry. Enhancement at signals by nitrogen- or helium-flushing.

J. Chromatogr. 541, 480-482 (1991). Description of a new, selective method for the detection of o-phenylenediamine and some of its derivatives on TLC plates by treating the chromatograms with Me trichloromethylacetimidate and exposing to pyridine vapor. Detection limits, between 80 and 2000 ng.

J. Chromatogr. A 724, 411-415 (1996). TLC of p-iodophenol and p-coumaric acid on cellulose with 0.1 M tris-HCl buffer (pH 8.5). Detection by spraying with a solution of 2mM luminol, 6 mM H2O2 and 0.744 U/mL peroxidase in a 0.094 M tris-HCl buffer (pH 8.5). Determination by densitometry with a single optical fibre that collected the emission signal to a spectrometer. Detection limit 38 ng and 14 ng respectively.

J. Planar Chromatogr. 13, 151-153 (2000). TLC separation of Cr, Mn, Fe, Co, Ni, Cu, Zn, Ag, Cd, Pb on cellulose with methanol - benzene - ethyl methyl ketone - 1-butanol - 25% NH3 6:4:4:3:3, methanol - benzene - ethyl acetate - ethyl methyl ketone - 25% NH3 5:4:5:3:3, and methanol - benzene - ethyl methyl ketone - 1-butanol - 2 M HCl 6:4:4:3:3. Detection after drying by spraying with a new visualization reagent, a 0.01% solution of 9-formylacridine in dichloromethane. The plates were then heated at 120°C for 10 min and examined under UV 366 nm.

J. Planar Chromatogr. 19, 4-9 (2006). TLC and HPTLC of 2-thioguanidine and 6-mercaptopurine on silica gel with methanol in a horizontal DS-chamber. Spots were visualized with a freshly prepared solution of sodium azide and starch, adjusted to a pH within the range 5.5-6.0, and then exposed to iodine vapor. The thiols became visible as white spots on a violet-gray background. The iodine-azide reagent enabled detection of quantities in the range 1-80 pmol per spot.

J. Chromatogr. A 1046 (2), 251-257 (2007). Fluorescence scanning densitometry of various analytes on HPTLC silica gel plates impregnated with a solution of coralyne cation, based on the increase or decrease, that the corresponding analyte induces on native coralyne emission at a given excitation wavelength. Compared to a procedure previously described for berberine cation, and Reichardt's dye probes, the sensitivity of coralyne in HPTLC detection of non-fluorescent, structurally different analytes (e.g. long-chain alkanes, alcohols, alkylbromides, neutral lipids) is superior.

J. Planar Chromatogr. 26, 517-520 (2013). TLC of amino acids on silica gel with 1-propanol - water 7:3. Detection by spraying with (1) 1 % 2-hydroxybenzenecarbaldehyde solution in propanone; or (2) 1 % 4-bromobenzenecarbaldehyde solution in propanone (2), followed by heating at 110 ºC for 10 min. After cooling, all plates (treated with (1) or (2)) were sprayed with ninhydrin (indane-1,2,3-trione monohydrate) reagent and air dried. Amino acid zones in various shades from yellow to brownish-red were detected (detailed table provided in paper). Plates were heated again at 110°C for 10 min and color changes were recorded. The LOD were determined visually by comparison of standard solutions (1 mg/L) and further dilution until no zone was seen. LOD for (1) and (2) were in the range of 0.1-1.0 µg/zone and 0.01-1.0 µg/zone, respectively.

J. Chromatogr. 333, 276-287 (1985). HPTLC of lacking native fluorescence but which can be converted to fluorescent derivatives: cholic acid, deoxycholic acid, hydroxycholic acid, glycocholic acid, lithocholic acid and taurocholic acid on silica with isooctane - ethyl acetate - formic acid - diisopropyl ether 5:4:1:1. Derivatization with 5 % perchloric acid in methanol.
