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.
