GPC/SEC System Automates Entire Sample Prep Process
Polymer Char has developed a reliable and fully automated 4D Gel Permeation Chromatography (GPC/SEC) system with significant improvement in the IR detectors to measure the composition and molar mass of polyolefins. The GPC-IR incorporates updated features such as the full integration of the infrared detector IR5 MCT, with enhanced sensitivity and stability to measure both concentration and composition (SCB/1000C). In addition, other detectors such as a four capillary bridge viscometer and a multi-angle light scattering for Long Chain Branching can be coupled to the unit, making it an advanced instrumentation for SEC analyses. The GPC system automates all sample preparation steps, including initial vials filling as well as an in-line filtration with blackflush cleaning. As a result, neither vials transfer nor manual solvents handling is required at any point throughout the analytical process. The system incorporates other technological developments, based on the principles of most reliable hardware, full automation, user-friendly operation, easy maintenance and proper diagnostic tools.
