Streamline material inspection in regulated industries with new Raman USP library

Sep 4, 2023

Article

Raman spectroscopy is a fast, easy, and specific method that simplifies material identification. This blog article explains how Metrohm’s Raman systems and Comprehensive USP Raman Library support regulated industries like pharmaceutical manufacturing. This support takes the form of streamlining inspection of deliveries, reducing inspection resources, facilitating delivery of raw materials to production, and ultimately getting the final product to the market faster.

Identification with Raman

Raman spectroscopy is classified as an identification test by the United States Pharmacopeia – USP <1225>. Identification tests are intended to ensure the identity of an analyte [1].

For Raman, this is achieved by comparing a sample spectrum to either:

  • the spectrum of a reference standard (identification) 

or

  • a spectral reference library acquired from a suitable number of similar materials which exhibit typical variation (manufacturer, batch, particle size, impurity profile, etc.) and comply with established specifications (verification) [2]
