Abstract : Forensic science plays an important role in crime analysis, in that forensic science covers a broad range of methods and techniques aimed at revealing relationships between people, scenes of crimes and objects, as well as helping to develop working hypotheses. Two types of physical evidence (ink and soil) are presented. The aim of ink analysis is to discriminated between local inks by using the following four techniques; UV-Vis, FL, Raman and EDX spectroscopy. About five fountain inks were examined. It was found that: (i) UV-Vis analysis was successful in characterizing fountain ink of different brands, (ii) FL analysis was successful in discriminating inks of different brands by considering spectra's intensities, (iii) Raman analysis revealed that each brands could be characterized and then differentiated by looking at the pattern of each spectra, (iv) The elemental profile identification provided by EDX contributes added points of comparison when determining product brands. While, the soil also examined by four techniques which are: Colors distinguish by the naked eye, chemical analysis, XRF and XRD. The study was carried out in Jeddah, K.S.A. In order to verify the difference between samples. The results of these studies show that analytical methods present high potential for forensic studies. The same approaches which were used in this thesis for forensic investigation can be applied in similar manner for quality control purposes.
