GPC system can be used to determine average molecular weight and molecular weight distribution for polymers, rubbers, plastics and synthetic fibers. It provides all the information necessary to identify physical properties of polymers. As even a little error in measuring average molecular weight or molecular weight can impact the physical properties of final polymer products considerably. Flow accuracy of pump and stability of RI Detector are critical factors for reliable GPC analysis. GPC work station adds simple and convenient control for GPC system.
