During a September 2022 webinar, Kyle Deluca (a senior scientist in engineering at Merck) highlighted bottlenecks in his group’s workflow for characterizing production of a pneumonia vaccine. In that process, purified components undergo chemical modification in a synthesis reactor, followed by buffer exchange, size-based separation, additional chemical modification, and final purification. Because the modification steps were time and labor intensive, Merck automated them. With support from Mettler Toledo, Deluca and Felix Milman (a specialist in engineering at Merck) described how…
