Corus 30-100 is a high-pressure chromatographic resin based on polystyrene-divinylbenzene. It has a large specific surface area, and excellent chemical and physical stability. Corus 30-100 has the advantages of high flow rate and high dynamic capacity, resistance to acid and alkali, and has a narrow pH operating range. The resin is used in reversed-phase chromatography (RPC) separation of small molecular compounds, peptides, low molecular weight proteins and other biomolecules.
