J. AOAC Int. 78, 585-591 (1995). After separation of sample components by TLC, the area corresponding to the Rf of the compound of interest is scraped off and eluted with immunoassay buffer. The ability of TLC to separate a series of compounds coupled with immunoassay determination of samples in parallel can provide an efficient, inexpensive, and rapid means of quantifying samples in more complex matrices.

CBS 95, 5-7 (2005). HPTLC of glyphosate and AMPA in surface water, in vitro-derivatized with FMOC, on silica gel (prewashed with 2-propanol by immersion for 24 h) with the organic layer of n-butanol - water - acetic acid 5:4:1 over 70 mm. Quantitative determination by fluorescence measurement with deuterium lamp at 268/M 360 nm. Linear calibration using peak area, LOD 50 ng/L.

J. Sep. Sci. 31, 71-77 (2008). HPTLC of acrylamide in drinking water on silica gel, derivatization in situ with 5-dimethylamino-naphtalene-1-sulfinic acid (1.6 µg/µL in methanol), followed by heating at 120 °C for 1 hour and developed with ethyl acetate. For fluorescence enhacement, the plate was dipped into a solution of 25 % polypropylene glycol in n-hexane and dried immediately. Quantitative determination by fluorescence at 366/>400 nm. Verification was based on HPTLC-ESI/MS, HPTLC-direct analysis in real time (DART)-TOF/MS and NMR. The hRf value of acrylamide (as 3-dansylpropanamide) was 69. Linearity was between 0.1 and 0.4 µg/L. Within-run precision and the mean between-run precision (n=3) were 4.6 and 11.0 %. The limit of detection and quantification for acrylamide was 0.025 and 0.083 µg/L, respectively. Recovery (by standard addition) was 96.4 %. The method showed comparable result with HPLC-MS/MS.

Encyclopedia of Chromatography Third Edition 1, 1749-1756 (2009). This review describes the current materials and techniques most widely used for the analysis of pesticides by TLC. In detail, information regarding sample preparation, stationary and mobile phases, detection and quantification is included. Specific examples of pesticides analysis in water and soil are also described.

J. AOAC Int. 93, 1757-1767 (2010). HPTLC of four mixtures of 21 pesticides on RP-18 by PPEC under different operating conditions. The samples were separated on a prewetted RP-18 phase with acetonitrile - buffer. Detection under UV light at 254 or 366 nm and in the range of 197 to 1033 nm with a DAD densitometer. Reproducible retention of pesticides was obtained; the reported separations are over 10 times faster than the corresponding separations by TLC.

J. Liq. Chromatogr. Relat. Technol. 37, 2846-2856 (2014). HPTLC fingerprinting of materials originated from cold surfaces of biomass fuel and fossils-fired home heating ovens, as well as truck exhaust systems and asphalt concrete samples on RP-18 with n-hexane. Fluorescence detection at UV 366 nm and absorbance detection (fluorescence inhibition) at UV 254 nm. The method can be used to identify wrong combustion parameters or unsuitable fuel.
