Gel Permeation Chromatography (GPC) also known as Size Exclusion Chromatography (SEC), is a very popular analytical tool for characterizing natural and synthetic polymers. This seminar will show excellent results possible with our Triple Detection GPC systems for various polyacrylonitrile (PAN) samples. Molecular weight distribution and structural information are of special interest to PAN research as well as product and process specifications. This presentation will show GPC data that differentiated PAN samples with copolymer and/or branching features. In addition, we will show that FIPA can be a fast and reliable tool for process control activities. Finally, we will review our well established Dilute Solution Viscometry (DSV) technology which is often used for product release specifications. DSV, when coupled with GPC and FIPA form a significant single vendor Polyacrylonitrile Characterization Technology Suite.
