Gel Permeation Chromatography (GPC) is a very popular analytical tool for characterizing natural and synthetic polymers. This Wednesday Dr. Wei Sen Wong will show results from Triple Detection GPC systems for various polyacrylonitrile (PAN) samples in a webinar presentation. Molecular weight (MW) distribution and structural information (Mark-Houwink plots) are of special interest to PAN research as well as for product and process specifications (QC). His presentation shows GPC data that differentiated PAN samples with copolymer and/or branching features. In addition, flow injection polymer analysis (FIPA) can be a fast and reliable tool for process control activities. Finally the well established Dilute Solution Viscometry (DSV) technology – often used for product release specifications – is presented. As Dr. Wong explains, the troika of GPC, FIPA and DSV form a useful Polyacrylonitrile Characterization Technology Suite. Sign up here to view the webinar or receive a recording.
