Anal. Chem. 77 (24), 8075–8085 (2006). Description of photoluminescence quenching experiments by oxygen for a series of transition metal dyes adsorbed on silica gel. The quenching kinetics showed differences regarding the behavior of the same dyes adsorbed to the well-defined surfaces of SBA-15 mesoporous silica particles and adsorbed to a thin layer-by-layer polymer film. Pore size and pore size distribution are larger for TLC silica than for mesoporous silica. On TLC silica the dye photoluminescence decay profiles show smaller deviations from an exponential form, and larger differences between the intensity and lifetime Stern-Volmer plots. Dyes adsorbed to TLC silica gel are three times more sensitive to quenching by oxygen.

J. Liqu. Chromatogr. 25, 1283-1294 (2002). TLC of red cabbage color, grape skin color, perilla color, elderberry color and cochineal color on RP-18 with acetonitrile - 0.2 mol/L trifluoroacetic acid 1:2. Measurement of visible spectrum by densitometry at 370-700 nm. A simple, rapid and reliable method.

J. Liq. Chromatogr. Relat. Technol. 32, 1273-1288 (2009). HPTLC of Sudan I (1), II (2), III (3), IV (4), Sudan Red B (5), Sudan Red 7B (6), Sudan Red G (7), Para Red (8), FD&C Orange 2 (9), Butter Yellow (10), Citrus Red 2 (11), Toluidine Red (12), and Disperse Orange 11 (13) in paprika, chili, and curry on RP-18 with acetonitrile - ammonia 25 % 19:1. Quantitative determination by absorbance measurement at absorption maxima of each dye. The hRf values of compounds (1) - (13) were 61, 54, 48, 29, 18, 11, 69, 63, 56, 48, 39, 18 and 11, respectively. Visual detection limits were 3 ppm for most dyes in either matrix, 5 ppm for Sudan I, 13 ppm for Disperse Orange, and 7 ppm for Butter Yellow. The limits of detection by densitometry were lower by a factor of 2 for all dyes and values of 1-3 ppm were reached except for Disperse Orange with a limit of detction of 7 ppm. Average recoveries ranged from 95.0-110.8 %. The HPTLC method is successfully applied in the routine control of illegal dyes in food by surveillance authorities.

Polimeros. 26, 68-74 (2016). TLC of additives such as the plasticizer acetyl tributyl citrate (ATBC) and phthalates like dioctyl phthalate (DOP) and dibutyl phthalate (DBP) in ink containing polyurethane and nitrocellulose resin on silica gel with ethyl acetate – ethanol – water 14:7:6 (1), toluene (2) or toluene – ethyl acetate 7:3 (3). Detection by spraying with 1 % 2,6 dichloro-p-benzoquinone-4-chlorimine in ethanol. The hRF values with mobile phases (1) to (3) were 97, 41 and 46 for ATBC, 94, 47 and 46 for DOP and 96, 45 and 46 for DBP, respectively.
