Raman spectroscopy is an optical analyzing method for measuring the vibrational attributes of molecules. Raman spectroscopy has advanced process analyses, providing improved resolution compositional data, linear response to concentration, non-destructive testing, and the ability to provide real-time measurements of samples without the requirement of carrier gases or a sampling system.
