Raman Spectroscopy Tackles Pharmaceutical Raw Materials

In recent years, Raman spectroscopy has gained a reputation in market segments that require the rapid identification of unknown compounds, such as the testing of high-purity chemicals, verification of pharmaceutical ingredients and the characterization of polymer materials. The surge of interest in Raman comes from modern instrumentation being equipped with intelligent decision-making software and onboard spectral libraries, which makes it an ideal technique for molecular fingerprinting purposes. Unlike traditional molecular spectroscopic techniques, Raman equipment can be used in a production environment or for field applications because it produces sharp, distinct peaks and requires virtually no sample pre-treatment or direct contact with the sample. Additionally, it has the unique capability of being able to test a sample directly through a transparent packing material like glass or plastic, with no impact on the spectral information.
