J. Planar Chromatogr. 33, 413-418 (2020). HPTLC of metanil yellow in colored sweets on silica gel with ethyl acetate - methanol - 25 % ammonia - water 35:11:5:5. Detection at UV 430 nm. The hRF value for metanil yellow was 56.
J. Planar Chromatogr. 33, 405-412 (2020). HPTLC of E-102 (1), E-124 (2), and E-133 (3) azo dyes with n-butanol - isopropanol - 25 % ammonia - water 13:4:2:1. Quantitative determination by absorbance measurement at 420 nm for (1), 335 nm for (2) and 410 nm for (3), respectively. The hRF values for (1) to (3) were 16, 18 and 36, respectively. Linearity was between 200 and 1000 ng/zone.
J. Planar Chromatogr. 33, 263-269 (2020). HPTLC of the interaction between methylene blue and purified glutathione-S-transferase (5 mmol/L methylene blue and enzyme solution in 0.1 mol/L potassium phosphate buffer) on silica gel with butanol - acetic acid - water 12:3:5 for 2 h. Detection by spraying with ninhydrin (0.25 % in acetone). The complex that most likely came from the interaction of methylene blue and purified glutathione-S-transferase had a hRf of 16.
J. Liq. Chromatogr. Relat. Technol. 43, 445-454 (2020). HPTLC of aniline (1), 2,4-xylidine (2) and 4-aminoazobenzene (3) in chili oils, pickles and related food matrices on silica gel with chloroform - acetic acid 9:1. Quantitative determination by absorbance measurement at 280 nm. The hRF values for (1) to (3) were 53, 43 and 82, respectively. Linearity was in the range of 2-14 ppm for (1) to (3). The LOD and LOQ were 0.0015 and 0.0045 ppm for (1), 400 and 1200 ppm for (2) and 200 and 600 ppm for (3), respectively. Mean recovery rate was 100.2 % for (1) and 100.9 % for (2). The azo aryl amines were also analyzed using a TLC-MS interface.
J. Planar Chromatogr. 32, 59-60 (2019). TLC of p-phenylenediamine on silica gel with ethyl acetate - diethyl ether 1:1. Detection by spraying with aqueous alkaline solution of Folin’s reagent (0.5 % Folin’s reagent in 5 % sodium carbonate solution). The hRF value of p-phenylenediamine was 45. The LOD for p-phenylenediamine was approximately 3 μg by visual evaluation.
J. Planar Chromatogr. 20, 381-384 (2007). Study of the retention behavior of 36 synthetic dyes in adsorption and reversed-phase TLC on zeolite layers with n-hexane, tetrahydrofuran, and bidistilled water. Significant linear correlations were found between the retention of the dyes chromatographed with the different mobile phases, proving the regular retention behavior of the analytes. No linear relationship was found between the physicochemical properties of the dyes and their retention, suggesting the separation capacity of zeolite differs markedly from that of silica and silica coated with hydrophobic ligands.
Chem. J. of Chinese Univ. 35 (4), 741-745 (2014). TLC is a rapid, simple, efficient, economic and widely used method with great advantages but some limitations in the detection of unknown groups. IR is a universal detection technique with advantages in the detection of colorless, non fluorescent substances. For successful application of TLC/FTIR the selection of the proper stationary phase is important. In this study sulfur fine particles were successfully employed as the coating for narrow band plates. Sulfur fine particles with the average size of 500 nm were produced by reaction of sodium thiosulfate with hydrochloric acid and characterized by XRS. Narrow band plates were coated by precipitation/evaporation technique. TLC of the mixture of rhodamine B and gentian violet on narrow band plates with tetrahydrofuran – methanol – ammonia 16:2:1 with chamber saturation for 10 min. TLC of the mixture of rhodamine B and bromophenol blue on narrow band plates with ethyl acetate – methanol – ammonia 16:1:3 with chamber saturation for 10 min. Both systems achieve complete separation. In situ detection of the separated zones by microscopic reflection infrared spectroscopy. The resulting spectra of the separated zones of rhodamine B, gentian violet and bromophenol blue matched those of the corresponding standards. There were no interfering absorption peaks except for the absorption peak of CO in the mid infrared region. The layer had a considerable ability for separation of mixed samples, therefore, the new type of stationary phase can meet the requirements for analyzing some mixtures by TLC/FTIR hyphenated technique.
