Agilent POLEFIN columns are useful for high-temperature organic GPC/SEC analysis of polyolefins with molecular weights from 100 to 30,000,000 Da. These organic GPC columns are based on a modified styrene-divinylbenzene copolymer network and have a maximum temperature rating of 210 °C. POLEFIN GPC columns offer flexible configurations, including two particle sizes and two different linear/mixed-bed columns to meet the needs for a variety of polymer analyses, such as polyethylene, polypropylene, and other polyolefins.
