The main advantages of large-scale multi-column countercurrent solvent gradient purification (MCSGP) over other purification methods are its ability to achieve high purity and yield of the final product, while also reducing solvents, waste, and operation time. That’s why Bachem as a leading manufacturer of peptide active pharmaceutical ingredients (APIs) established large-scale MCSGP ready for further use in the GMP production of peptide APIs. Ralf Eisenhuth will take you on a journey from starting with small-scale MCSGP experiments in 2017 up to today’s large-scale MCSGP purification at Bachem. He will share data from process development and manufacturing, as well as insights on control strategies and the process mass intensity of MCSGP processes.
