The United States, Food and Drug Administration (FDA) Conducts a Comprehensive study using Tornado’s HTVS-enabled Hypeflux PRO Plus (HFPP) and Bioimmersion probe.


The study, Raman Spectrometry as a tool to study minimization of batch age effects and make product quality decisions for biotherapeutic antibody production, was shared at the 2023 FDA Science Forum at the Product Development and Manufacturing session.

The study illustrates the value of Raman Spectroscopy as a relevant cost-saving PAT tool while elucidating methods to enhance or achieve superior outcomes using the technique. According to the study, Raman’s ability to non-destructively assay chemical composition and molecular structure using visible or near-infrared radiation makes it an ideal PAT to monitor bioreactor conditions in real-time, it uses the illustration of applications such as upstream manufacturing of biotechnology products, where real-time monitoring, feed-back, and control can result in substantial cost and time savings.

Raman spectroscopy presents an exciting opportunity as an emerging technology for monitoring and modeling critical quality parameters during the production of protein therapeutics. While it offers tremendous potential, it’s essential to acknowledge that the performance of Raman models may sometimes be influenced by batch age effects. In this study, we will showcase effective techniques to quantify and mitigate the influence of these effects, ultimately leading to more robust and reliable models.

Due to the complexity of Raman spectra, multivariate calibration models are used. This study aims to reveal that frequently employed model summary statistics may exaggerate the reproducibility of multivariate calibration models developed using data from upstream biomanufacturing processes. Additionally, it illustrates how the model’s reliance on component collinearity can be assessed through its score space and demonstrates the utility of supplementation experiments in reducing the model’s dependency on component collinearity.
