Raman spectroscopy is used in biomanufacturing as a process analytical technology (PAT) tool for making rapid, nondestructive, in-process measurements. However, Raman data collection at early stages of bioprocess development has been a challenge because of the lack of interface to bioreactors <250 mL. Realizing the industry was struggling to capitalize on the full potential of Raman spectroscopy, Kaiser Optical Systems, Inc. (Kaiser), an Endress+Hauser company, collaborated with Sartorius to bring Raman to Ambr 15 microbioreactors (10–15 mL) and Ambr 250…
