Material characterization testing can include Polymer Molecular Weight Determination and distribution utilizing Gel Permeation Chromatography (GPC) and using Refractive Index detection. Once the Molecular weight distribution of a polymer material is known, the Inherent Viscosity can be measured and mapped back to the GPC data to determine average Molecular Weight values. This provides a quick Quality Control check that can detect lot to lot variations. Inherent and Intrinsic viscosity measurements are determined using our automated viscometer.
