Cover Story: To accelerate the precipitation towards autonomous operation, the integration of real-time release testing is essential to implement a suitable process control. Therefore, the feasibility of online measurement techniques including Raman, FTIR, DAD, and fluorescence is demonstrated as PAT technology. To apply the online measured data to the process, a process model (digital twin) must be developed to pave the way for processing feedback-control. With the aid of the model and the online measurement of critical quality attributes (CQAs), the monitoring of process can be conducted, as well as the optimization of operation. In this way autonomous operation becomes feasible. View this paper
