TECHNOLOGY FOR THE ANALYSIS OF TRACE EVIDENCE

 

Raman Spectroscopy

 

Raman spectroscopy is a powerful analytical tool that is widely used in forensic science for the examination of paint chips, fibres, inks and controlled substances, as well as residues form explosives, flammables and accelerants.


Specific to molecular structure, Raman spectra provide valuable "signatures" for comparing and differentiating materials.

By installing the wide range of databases that Foster + Freeman offer, unknowns can be identified, as most substances produce unique Raman spectra.
