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.
J. Liq. Chromatogr. Relat. Technol. 40, 259-281 (2017). Research communication on chromatographic properties of 18 colorants including amaranth, black PN, bromophenol blue, bromocresol green, bromocresol purple, bromothymol blue, carmine, dimethyl yellow, erythrosine, fluorescein, methyl red, naphthalene black, patent blue, phenol red, Sudan II, Sudan III, Sudan IV, and p-xylenol blue. The paper presents a comprehensive retention database for designing 1D and 2D planar separations systems.
J. Liquid Chromatogr. 14, 1461-1467 (1991). TLC of synthetic dyes on antimonic acid and on admixture of antimonic acid and silica with butanol – acetic acid – water 5:1:2. Discussion of the separation potential of the stationary phase.
InCom-Sonderband, 1-6 (1997). Comparison of the capabilities of two chromatographic methods, gas chromatography/mass spectrometry and densitometric thin-layer chromatography, for solving an important problem of forensic analysis, namely, determining the age of writing inks on questioned documents. GC/MS analyzing ink volatile components has certain advantages compared with TLC dealing with ink dye components. Details for densitometric TLC see R. L. Brunelle, Intern. J. of Forensic Document Examiners 1, 94-98 (1995).
Proc. Ros. Acad. Sci. 399 (3), 362-365 (2004). Determination of colorants (rhodamine B, brilliant green and rhodamine G) on silica gel (sorbphil, Sorbpolymer, Russia) with ethanol (amperage 220 µA), ethanol and 0,01 % LiCl (475 µA), acetonitril - water 9:1 (430 µA), acetonitril - water 9:1 and 0,01 % LiCl (830 µA) or silica gel (Merck) with ethanol (amperage 240 µA), ethanol and 0,01 % LiCl (650 µA), acetonitril - water 9:1 (360 µA), acetonitril - water 9:1 and 0,01 % LiCl (950 µA). Frequently used voltage is 1 kV. All the plates are covered with polyethylene film to prevent evaporation of mobile phase.
