Infared Detectors

IR4


IR4 is a dual wavelength infrared detector, which uses the principle of infrared absorption spectroscopy to measure the concentration and composition in Polyolefins.

IR4 is the detector used in all Polymer Char analytical instruments and was designed to determine the on-line concentration and composition in HPLC, GPC or to be coupled with other separation techniques like CRYSTAF, TREF, etc., and it has been showed to be the most appropriate detector for Polyolefins.
