Original Abstract

Abstract

An HPLC-DAD-MS method is described to analyse textile dyes in different dye classes (reactive, basic, acid, direct, disperse). The described method is sensitive enough to analyse single fi bres with a length of a few mm or less, which makes it suitable for forensic analyses. The current paper describes the information content of the acquired data and as well as the results of a validation study, in which the repeatability, specifi city and limit of detection of the method were assessed by repeated measurements of nine different dyes in the mentioned dye classes. The mass accuracy (deviation generally < 2 ppm) and absorbance spectra were found to be highly stable in several easurements over a period of 8 weeks. Deviation in retention times were observed and attributed to small experimental effects and a pre-column blockage. The results show that dye analysis is possible for most fi bres with a minimum length of one or a few mm.
