Fully-automated high temperature GPC/SEC system with highly sensitive Infrared Detector for Molar Mass Distribution and chemical composition analysis of Polyolefins.
With over 20 years of experience in the development of high temperature instruments for polyolefin analysis, Polymer Char offers the GPC-IR® instrument, a reliable multiple detector Gel Permeation Chromatography (GPC) system dedicated to the characterization 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 characterization of polymers such as HDPE, PP, LDPE, LLDPE, EP copolymers, EVA, EBA and others in the group of polyolefins.
Two different infrared detectors are available: the most modern IR5 MCT, with enhanced sensitivity and stability to measure concentration and chemical composition (SCB/1000TC); and the classic IR4, which offers a broader spectral range enabling analysis of the carbonyl group containing copolymers. Other detectors that can be coupled to the GPC-IR® system are Polymer Char’s four-capillary bridge viscometer and a Multi-Angle Light Scattering (DAWN® HELEOS II™ by Wyatt Technology®), for the determination of absolute molar mass and study of Long Chain Branching (LCB). Thus, becoming 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.
Finally, data processing becomes simple and powerful thanks to the GPC One® Software, a comprehensive calculations software package developed in collaboration with the industry leaders that integrates all detectors’ signals.
Polymer Char’s GPC-IR® represents a new generation of instruments for polyolefin characterization in terms of repeatability, automation, and reliability.
