IMPROVING THE QUALITY OF FORENSIC TRACE EVIDENCE Raman spectrometers specifically designed for the examination of forensic evidence Fast, non-destructive and highly effective, Raman spectroscopy is an ideal technique for identifying and comparing substances of forensic value. ® Unlike other Raman systems, Foram 3 spectrometers have been developed specifically for forensic examinations and include dedicated casework management software providing automatic spectral comparisons and data archiving with search and match facilities. Foram®3 systems can be further enhanced through the addition of a comprehensive library of forensic Raman spectra for the identification of unknowns.

COMPACT RAMAN SPECTROMETERS DESIGNED TO MEET THE CHALLENGE OF FORENSIC ANALYSIS Providing rapid, non-destructive, chemical analysis, Raman spectroscopy is a valuable analytical tool with wide ranging applications. Foster + Freeman Foram®3 instruments offer forensic scientists the full analytical power of Raman, in a choice of laser wavelengths, tailored to meet the specific demands of forensic science with data archiving and casework software and optional spectra databases to aid in the identification of unknown substances. The compact easy-to-use systems can be operated via a laptop, making...

Raman as a Forensic Tool Raman spectra exhibit numerous features that are specific to molecular structure providing valuable "signatures" for comparing and differentiating materials, making it an ideal technique for the analysis and identification of forensic trace evidence including: • • • • • Explosives, accelerants and gunshot residues (GSR) Illicit drugs and their precursors Paint chips and smears Pen and printer inks Fibres and materials Questioned Documents Pen and Printer Inks Analysing the pigment based ink in Gel Pens presents document examiners with a unique challenge. In-house studies...
