J. Planar Chromatogr. 2, 297-303 (1989). HPTLC of 10 fungicides (captafol, captan, cymoxanil, dichlofuanid, dithianon, folpet, iprodione, procymidone, vinclozolin, triadimefon) on prewashed silica (100 µm) with toluene - hexane - diisopropyl ether - ethyl acetate 667:20:8:5. Detection and quantitative determination by densitometry.

J. Planar Chromatogr. 7, 461-463 (1994). TLC on silica with benzene - ethyl acetate 10:1. Detection under daylight and UV 254 nm.

Dünnschicht-Chromatographie InCom Sonderband 1996, 157-165. HPTLC of benzo[g,h,i]perylene, indeno[1,2,3]pyrene, benzo[a]pyrene, benzo[b]fluoroanthene, benzo[k]fluoroanthene and fluoroanthene on caffeine-impregnated silica prewashed with dichloromethane, precooled for 30 min at -20 °C, with dichloromethane at -20 °C. After removal of the eluent the plates are dipped for 2 s into a solution of paraffin (low viscosity)/n-hexane 1:2 and dried again (for stabilization and intensification of the inherent fluorescence of the PAH). Quantification by densitometry.

J. Planar Chromatogr. 18, 388-390 (2005). TLC of haloperidol and metabolites on RP-18 previously equilibrated for 30 min with methanol containing 0.001 % triethylamine at 27 +/- 1 °C (room temperature). Detection by treatment with iodine vapor. Quantitative determination at 230 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.

Rapid Commun. Mass Spectrom. 24, 1721-1729 (2010). Ambient proximal probe thermal desorption (TD) sampling of substances from a HPTLC plate and coupled with secondary ionization by atmospheric pressure chemical ionization (APCI) or electrospray ionization (ESI). The method does not require a specialized ionization source. Different anaytical parameters and performance metrics are reported and the method covers a wide range of analyte types including explosives, dyestuffs, herbicides and pharmaceuticals.
