Upgrading from Single- to a Multi-Detector Gel-Permeation Chromatography (GPC) for Polymer Characterization

Single-detector systems, also known as conventional gel-permeation chromatography (GPC), feature a refractive index (RI) detector, and are used for making molecular weight measurements by comparing the elution time of a sample against the standards of a known molecular weight.
