Chromatogr. 2, 287-289 (1985).(Chinese) (Application of the chord distance method to the selection of thin-layer chromatography and paper chromatography optimal combination.) Study on the cluster analysis by using weighted pair-group and shortest distance methods for TLC of 26 food dyes with 10 developing systems. Method optimization. The same study was made for paper chromatography of 14 amino acids with 5 developing system. The results showed advantages of the method.
J. Planar Chromatogr. 7, 211-216 (1994). TLC of the individual dye components of a hair color product (eight different variations of the formula) on silica with ethyl acetate or ether - chloroform - ethyl acetate 6:1:1. Quantification by densitometry at 415 nm (absorbance).
J. Planar Chromatogr. 21, 89-96 (2008). TLC of dyes in normal-phase systems on silica gel, diol phase, cyano phase, and amino phase, and in reversed-phase systems on cyano phase, Diol phase, amino phase, and RP-18. RP chromatography with different mobile phase modifiers (THF, dioxan, methanol, acetonitrile, and acetone) at different concentrations, containing different amines, cationic and anionic ion-pair reagents, buffers, and ammonia, again at different concentrations. Based on the results the best system was selected: HPTLC of tartrazine, sunset yellow FCF, allura red AC, ponceau 4R, brilliant blue FCF, indigotine, brilliant black PN, quinoline yellow, patent blue V, brilliant green BS, azorubin, and brown HT on RP-18 with acetate buffer pH 3.5 containing 15-25 % modifier and 0.025 M propylamine or diethylamine. Detection in white light and under UV 254 and 366 nm. Quantitation by diode array densitometry in the range of 191 to 1033 nm.
Textile Auxiliaries 10, 47-50 (2013). Staining of textiles often uses several dyes matching in color, and a change in the dye concentration of the staining solution influences the dye uptake rate in the dyeing process, and thus affects the dyeing result. The real-time monitoring of the dye concentration in the dyeing process can reflect the state of dyeing and allows for more reasonable working processes and staining formulas. A TLC method is presented for multi-wavelength scanning of the dyes cationic yellow X-5GL and X-8GL on silica gel without the need for chromatogram development. An oblique projection algorithm was based on the oblique projection theory. This theory describes a multi variable system with data space and establishes a pure signal separation model which allows to differentiate the measured vector spectrum signal of the interested component from the mixed spectrum signal and determine its content by chemometrics. The obtained results were compared with those by using conventional TLC on silica gel developed with ethanol, followed by densitometric evaluation. It was found that the measured precision for the presented method was lower than that of traditional TLC.
Food Control. 79, 258-265 (2017). TLC-surface-enhanced Raman scattering of Sudan I in food on diatomite earth TLC plates fabricated by spin coating diatomite on glass slides with cyclohexane – ethyl acetate 6:1. Detection by depositing 2 mL concentrated gold nanoparticles three times. Quantification using a Raman microscope equipped with a CCD detector to acquire the surface-enhanced Raman scattering spectra. Excitation wavelength was 785 nm and the laser spot size was 2 mm in diameter. The method allowed for the determination of Sudan I in chili sauce down to 1 ppm (0.5 ng/zone) without sample preprocessing.
I. Synthesis and characterisation of terminal ring isomers of C.I. Reactive blue 2. J. Chromatogr. 435, 127-137 (1988). TLC of the reaction product and hydrolytic by-products of terminal ring isomers of the reactive anthraquinone dye C.I. Reactive blue 2 on silica with butan-1-ol - propan-2-ol - ethyl acetate - water 2:4:1:3.
J. Planar Chromatogr. 4, 167-169 (1991). Description of a TLC method for the discrimination between samples having a similar appearance and a very similar quantitative composition. TLC separation of aqueous solutions of Acid Brilliant Blue Z and Acid Anthraquinone Brillionat Blue on silica with ethyl acetate – isopropanol – water – acetic acid 30:15:10:1. Densitometry by absorbance at 580 nm; comparison of peak height values.
(Determination of blue food dye no 3 in Blue Curaçao.) LaborPraxis 1, 30-32 (1993). HPTLC of the sodium or calcium salt of 2,4-disulfo-5-hydroxy-4',4'-bis-(diethylamino)-triphenylcarbinol (E131) on silica with butanol - water - acetic acid 4:2:1. Quantification by densitometry at 639 nm.
