Raman Spectroscopic Fingerprint of Intermediates in Biotechnological Reactions - A Multimodal Spectroscopic Approach

The application of Process Analytical Technology (PAT) for biotechnology has several limitations including:

1. Working in an aqueous matrix with low component concentrations
2. Complex component mixtures
3. Photon scattering with changing path lengths

Due to the above limitations, highly selective and highly sensitive techniques combined with intelligent chemometric tools are required for successful biotechnology applications.

This webinar will begin with a short discussion and comparison of the spectroscopic methods with emphasis on applicability to aqueous systems with low component concentrations. Dr. Kessler will outline how to use scatter as information and not as limitation for the spectroscopic analysis of opaque systems. It will be shown that the combination of Raman spectroscopy and Multivariate Curve Resolution (MCR) provides a powerful tool to analyze complex biochemical reactions. An example will be given where the laccase-catalysed transformation of indigo carmine was studied and how intermediates can be characterized using Raman spectroscopy and MCR for underlying mechanistic interpretation.
