ffTA Foram X3 multi-wavelength Raman spectroscopy
Raman spectroscopy is a powerful analytical tool that is widely used in forensic science for the study of a variety of organic and inorganic materials including paint chips, fibres, inks, controlled substances, precursors, pesticides as well as residues from explosives, flammables and accelerants.
Through the analysis of Raman spectra, specific to molecular structure, this powerful module is able to provide valuable "fingerprints" for comparing, differentiating and identifying materials. By installing the wide range of databases that Foster + Freeman offer, ‘unknowns’ can be identified, as many substances produce unique Raman signatures.
Equipped with a choice of one or three laser wavelengths 785nm (invisible), 638nm and 532nm, the Foram X3 module is a uniquely versatile device.
High levels of sensitivity can be achieved with the 532nm laser, while the 785nm, infrared laser is better able to suppress fluorescence. A balance between power and sensitivity can be achieved through the use of the 638nm laser.
