Working principle / output
Raman spectrometry is used to determine the chemical nature of a sample, its molecular structure and crystallinity. It is a non-destructive technique, based on the measurement of the atomic/molecular vibration frequencies of materials under the impulse of a laser beam. Raman analysis is based on the same principle as Fourier Transform InfraRed (FTIR) spectroscopy but with a better spatial resolution. Qualitative (or even semi-quantitative) measurements can be made on solid, liquid or gaseous samples, both of organic and inorganic origin.
