Aseptic Identification of Polysorbates using Handheld Raman

AppNote RAD008: Aseptic Identification of Polysorbates

A feasibility study was performed to determine if polysorbate 20 and polysorbate 80 from three different vendors could be identified via analysis through their original, amber bottle packaging.


Because polysorbates are reactive to light and air, packaging is usually in thick, dark, amber bottles. For the identification of many polysorbates in amber bottles, Progeny can provide quick verification results without risking quality and sterility of the material by opening the container.
