Aseptic Identification of Polysorbates using Handheld Raman

This application note details a feasibility study performed to determine if polysorbate 20 and polysorbate 80 from three different vendors could be identified and distinguished via analysis through their original, amber bottle packaging using a handheld 785nm excitation analyzer and Progeny, which uses a 1064nm excitation laser to reduce fluorescence interference.
