Development and validation of a selective marker-based quantification of polysorbate 20 in biopharmaceutical formulations using UPLC QDa detection

Polysorbates are broadly used as non-ionic surfactant in biopharmaceutical formulations. Lately, the degradation of polysorbate moved into the main target of consideration, as a result of in a number of revealed research it was described, that stability points in polysorbate containing formulations have been noticed resulting in the formation and look of sub-visible and visual […]
