Currently, Raman spectroscopy (RS) is rapidly becoming a mature analytical technique in the pharmaceutical world. Thus far, it is used almost exclusively in a stand-alone mode, since coupling with liquid separation methods hardly seemed realistic in practice. However, as outlined in this article, recent developments are quite promising and such combinations of techniques have a distinct potential.

Raman spectroscopy is a highly versatile tool that provides chemical fingerprints from biological material that can be interpreted using chemometrics and machine learning. In combination this powerful approach is being developed for the quantitative determination of multiple determinands in bioprocesses and for the characterisation of microorganisms.

Traditionally, analyses in pharmaceutical research and industry were often performed using Nuclear Magnetic Resonance (NMR) or Mass Spectrometry (MS). However, researchers are aware that Raman Spectroscopy possesses advantageous characteristics for the pharmaceutical world.

Raman spectroscopy using excitation in the near infrared allows non-destructive Raman analyses of pharmaceutical products as well as of plant or animal tissues. This radiation excites only minimal fluorescence of the samples or impurities and has only minimal photo-physical and photochemical activity. Raman analysis of plants allows the efficient exploration of new sources of raw materials for phytomedicinal drugs.
