Thin-layer chromatography (TLC) is a valuable analytical technique for separating and analyzing organic compounds. In dye analysis, for example, TLC is used to identify dyes in fabrics or fibers (forensics) and to determine the composition of natural dyes in plants and animals. In this demonstration, thin layer chromatography will be used to separate mixtures of dyes.
