Fast, easy and reliable – Flow Injection Polymer Analysis for QA/QC and Process Control

Gel Permeation Chromatography (GPC) also known as Size Exclusion Chromatography (SEC), is a very popular analytical tool for characterizing the molecular weight and structure of natural and synthetic polymers. Such information is important for both research and quality control (QC) applications, however, in the QC environment repeatability and sample throughput are often more critical. Flow Injection Polymer Analysis (FIPA) is a useful alternative to conventional GPC for QC applications due to its shorter elution time and can be performed on a standard GPC instrument with a simple switch of column selection valve. In this presentation we will compare the benefits of 'information rich' GPC against the 'faster and more repeatable' data generated using FIPA for Polyacrylonitrile and Polycarbonate materials.
