Application of modern chemical analysis to practical scientific and technical situations, with particular emphasis on producing evidence for use in the judicial system.

This paper focuses on the application of modern analytical techniques used to support the legal system in providing forensic evidence. It also provides a sound analytical training and is recommended to all experimental chemists.Drawing strongly on examples from case studies, the paper provides the theoretical and practical framework for applying spectroscopic techniques for identification, quantification and fingerprinting of various materials, such as drugs, accelerants, environmental contaminants, materials and physical evidence. The emphasis of this paper is on the practical skills gained in the laboratory. The laboratory course is constructed to provide training in basic analytical chemistry before advancing to more sophisticated analytical techniques.
