The purification requirements in the biopharmaceutical industry will be even more demanding in the coming years due to increased awareness of product-related impurities like oligomers, variants, positional isomers, and glycoforms. These impurities need to be separated from the final product. Dr. Raja Ghosh’s work focuses on the design and development of efficient chromatography devices that combine high-speed with high-resolution in separation. He speaks with Dr. David Wood of the Ohio State University about how the chromatography devices he is developing address these challenges.
