Comprehensive and Fully-Automated Solution for High Temperature GPC/SEC in Polyolefins

Dec 24 2016 Comments 0

Polymer Char’s GPC-IR® instrument is a reliable multiple detector Gel Permeation Chromatography (GPC) system dedicated to the characterisation of polyolefins. It incorporates high-stability infrared (IR) detectors with outstanding baseline and simultaneous detection of total concentration and chemical composition, which adds a new dimension to the GPC analysis. The built-in IR detection provides the most comprehensive characterisation of polymers such as HDPE, PP, LDPE, LLDPE, EP copolymers, EVA, EBA and others in the group of polyolefins, and the possibility of coupling Viscometer and Light Scattering (DAWN® HELEOS II™ by Wyatt Technology®) results in the most complete, four-detectors, instrument for polyolefin analysis.

Polymer Char’s GPC-IR automatically performs all sample preparation steps including the initial filling of vials with solvent and in-line filtration. As a result, neither vial transfer nor manual handling of solvent is required throughout the whole analytical process. Other key automation features are incorporated to overcome historical problems usually arisen when working with high temperature GPC/SEC analysis, including the company’s Sample Care protocols that preserve the sample integrity along the whole analytical cycle.

Polymer Char’s GPC-IR represents a new generation of instruments for polyolefin characterisation in terms of repeatability, automation, and reliability.
