Application


  • Effect of salt modulators on the elution behavior of insulin and the separation of product-related impurities in reversed-phase chromatography.: The study examines how potassium sulfate and other salts affect the chromatography process, specifically focusing on insulin purification. The results are crucial for optimizing chromatographic methods in pharmaceutical production (Koch et al., 2023).
