about the Event

In 2021, Bachem acquired the first two process-scale Multicolumn Counter-current Solvent Gradient Purification (MCSGP) systems for the purification of peptides and oligonucleotides. The systems are qualified for GMP use for which first purifications at scale were successfully performed. In this webinar, our efforts to establish large-scale MCSGP will be presented, starting from initial small-scale experiments in 2017 to the first large-scale API purification in 2022. Besides showing real data from process development and manufacturing, we will provide insights regarding potential control strategies as well as the general workflow for process-scale MCSGP purification of large synthetic molecules.
