About this talk

Raman spectroscopy has been seen as spectroscopic tool used in bioprocessing to monitor and control cell metabolism to optimize quality and yield of titer. This is due to Raman’s insensitivity to water and ability to analyze samples without manipulation. However there are certain challenges for Raman when analyzing a complex and dynamic sample such as a cell culture. This article will describe the different challenges in analyzing in-line Raman data and how to mitigate changes in samples that include changes in fluorescence background, presence of cells/debris in samples, and spectral interference.
