Buffer preparation is both time-and space-consuming and can easily become a challenge in biomanufacturing. This application note describes a lean approach to buffer preparation by implementing in-line conditioning (IC). Buffers of different formulations for a mAb chromatography capture step were prepared in an automated, consecutive manner, minimizing manual interactions. To further reduce the time and space required for buffer preparation, ready-made, highly concentrated, low-volume stock solutions were used. Feedback regulation of the final buffers, using dynamic control, ensured accurate formulations.
