Quantification of Crystallinity Using Transmission Raman Spectroscopy
26 Feb 2019The crystallinity of an active pharmaceutical ingredient (API) may affect its bio‑availability and its overall patient efficacy. It is critical to be able to measure the crystalline content of a final drug product. Transmission Raman spectroscopy (TRS) can differentiate and quantify crystalline and amorphous API. Measurements are fast, and the transmission sampling geometry ensures that the signal obtained is representative of the bulk, and not biased to the surface

Raman SpectroscopyRaman spectroscopy is used to discern the vibrational and rotational states of molecules and hence the chemical composition of a sample by measuring the inelastic scattering of monochromatic light. Explore a range of Raman spectrometers, including handheld/portable Raman spectrometers for QC/QA labs and in situ spectrometers for processes. Conduct Raman imaging for microanalysis of mixed samples using a Raman microscope. Raman spectrographs are also available.

The remaining inactive components are known as excipients.
