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.

J. Planar Chromatogr. 2, 62-64 (1989). Post-chromatographic derivatization, viz. gas phase derivatization, mainly of polar structures, in an aluminum-aluminate reactor to give fluorescent products. Examples of cola, wine, orange juice etc. were derivatized to fluorescent spots, which were measured by in situ scanning.

J. Chromatogr. 537, 494-496 (1991). TLC of 20 amino cards on silica with butanol - acetic acid - water 40:5:7. Detection by spraying with a freshly prepared solution of formaldehyde (37%, 15 mL) + acetyl acetone (7.8 mL), diluted to 100 mL with acetate buffer (pH 4.7), and by heating at 100 °C for 10 min. Detection limits, 0.26 x 10-4 - 6.9 x 10-4 mmol. Comparison of the sensitivity of this reagent with ninhydrin reagent.

J. Planar Chromatogr. 9, 212-214 (1996). TLC of 12 toxic cations (Fe, Co, Ni, Cd, Cu, Pb, Hg, Hg2, Cr, Zn, Sb, Mn) on a mixture of DEAE cellulose and silica with isopropanol - ethanol - 5 N HCl 5:5:1. Identification with 0.1 % ethanolic solutions of pyridine-2-aldehyde-2-furoylhydrazone and rubeanic acid.

J. Planar Chromatogr. 13, 199-204 (2000). TLC of 42 different arylamines, naphthylamines, aliphatic amines, hydrazines and hydrazides, diamines and dihydroquinolines on silica gel with ethyl acetate - hexane 1:3; 1:2, toluene, ethanol, chloroform - ethyl acetate - ethanol 6:6:1, ethyl acetate, and hexane - benzene - acetone - ethanol 25:25:2:15. Visualization either with 4-chloro-5,7-dinitrobenzofurazan or 7-chloro-4,6-dinitrobenzofuroxan (0.15 g in 100 mL acetonitrile).

J. Planar Chromatogr. 19, 348-354 (2006). HPTLC of puerarin, daidzein, daidzin, and 3’-methoxypuerarin on silica gel, pre-washed with methanol, in an unsaturated twin-trough chamber with chloroform - methanol - ethyl acetate - water 16.2:18.8:52:3. Quantitative determination by absorbance measurement at 254 nm. The relative standard deviation of Rf values, retention times and peak area percentages all meet the national standards.
