The Need and Evolution of IR Detection for Polyolefin Analysis The full characterization of polyolefins requires separation techniques with specific detectors that provide information about the microstructure, such as the high-temperature GPC/SEC analysis with Infrared Detection. Polymer Char, the leading company in infrared detection technology applied to polyolefins, developed and launched the polyolefin-dedicated detectors IR4 and IR5. These detectors have been extensively used in the polyolefin characterization field over the . . . read more »
