Portable Raman Spectroscopy in Forensics : Explosive Residues and Inflammable Liquids

Portable Raman Spectroscopy Forensics

The transition from traditional chemical tests to modern analytical techniques is the current state in many forensic laboratories. Particularly, spectroscopic techniques are showing an increase in their potential applications in the forensic field due to the novel instrumentation which is being developed to be faster, more sensitive, more compact and portable and more flexible to analyse a wider variety of substances. In addition, spectral libraries containing a larger number of spectra for a variety of compounds are being created, facilitating this method of identification of samples under suspicion. Portable Raman spectroscopy is one of these novel spectroscopic techniques. The suitability and potential of Raman spectroscopy in forensics is widely known by forensic specialists who use it in the laboratory to identify a wide variety of compounds including explosives, drugs, paints, textile fibers and inks [5]. However, the use of laboratory-grade Raman outside the laboratory, such as for in-situ analysis at a crime scene, was something thought possible only in forensic-fiction until just a few years ago. Fortunately, modern portable Raman spectrometers are commercially available, and their instrumental features are comparable to Raman lab- spectrometers.
