Material characterization testing can include 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.
