The Selection of Noncorrelated Thin-Layer Chromatographic (TLC) Solvent Systems for the Comparison of Dyes Extracted from Transferred Fibers

CODEN: JFSCAS

Abstract

The potential of using a combination of normal and reverse phase thin-layer chromatography for the comparison of disperse, acid, and reactive dyes extracted from textile fibers of forensic science origin was examined. For disperse and acid dyes, the use of a normal silica gel and a reverse phase system was shown to provide a pair of systems of low correlation. In contrast, the use of two silica gel systems provided a pair of highly correlated systems that possibly offered little more additional information than a single system. A suitable reverse phase system for the separation of reactive dyes was not found. The various pairs of silica gel systems tested for reactive dyes were all shown to be highly correlated.
