Abstract: | Thin-layer chromatographic systems are described for the analysis of various preformed metal complex dyes (aluminon-chromium(III), carminic acid-aluminum, carminic acid-chromium(III), carminic acid-iron(III), oelestine blue-chromium(III), gallamine blue-chromium(III), gallocyanin-chromium(III), hematein-aluminum, hematein-chromium(III), purpurin-aluminum) and their parent dyes. Certain of there dyes have also been analysed by agar-gel electrophoresis or gel-filtration chromatography. The merits of the three analytical methods are discussed. |
