We get some FAQs here in the analytical lab…one recurring question here at Gateway is “Why did/didn’t you do Raman?” During foreign particulate matter investigations, the use of spectroscopy is pretty common. Spectroscopy allows us to study the way a material interacts with energy, in order to identify a material. Sometimes, a scientist may use FTIR (Fourier Transform Infrared Spectroscopy)(1) …sometimes, Raman(2) may be chosen as the choice method; however, there are times where both methods are employed.
