USAGE OF FT-IR MICROSCOPE IN FORENSIC EXAMINATION OF BLUE COTTONE MATERIAL

In forensic textile examinations one of the often encountered problems is potential overlap of target fibres in terms of visual characteristics (especially colour). This is why usual identification methods like comparison microscopy and microspectrophotometry are not enough and it is necessary to turn to “destructive” methods like thin layer chromatography (TLC). Since destructive methods are the last resort in forensic science, in this paper probability of using of FT-IR method instead of TLC was investigated in order to identify differences between blue cotton samples.
