  • Description: <jats:title>Abstract</jats:title><jats:p>The biopharmaceutical industry is transitioning from currently deployed batch‐mode bioprocessing to a highly efficient and agile next‐generation bioprocessing with the adaptation of continuous bioprocessing, which reduces capital investment and operational costs. Continuous bioprocessing, aligned with FDA's quality‐by‐design platform, is designed to develop robust processes to deliver safe and effective drugs. With the deployment of knowledge‐based operations, product quality can be built into the process to achieve desired critical quality attributes (CQAs) with reduced variability. To facilitate next‐generation continuous bioprocessing, it is essential to embrace a fundamental shift‐in‐paradigm from “quality‐by‐testing” to “quality‐by‐design,” which requires the deployment of process analytical technologies (PAT). With the adaptation of PAT, a systematic approach of process and product understanding and timely process control are feasible. Deployment of PAT tools for real‐time monitoring of CQAs and feedback control is critical for continuous bioprocessing. Given the current deficiency in PAT tools to support continuous bioprocessing, we have integrated Infinity 2D‐LC with a post‐flow‐splitter in conjunction with the SegFlow autosampler to the bioreactors. With this integrated system, we have established a platform for online measurements of titer and CQAs of monoclonal antibodies as well as amino acid analysis of bioreactor cell culture.</jats:p>
