IR4 is a dual wavelength stand-alone infrared detector, which uses the principle of infrared absorption spectroscopy to measure the concentration and composition in Polyolefins. Overview IR4 is a dual wavelength stand-alone infrared detector, which uses the principle of infrared absorption spectroscopy to measure the concentration and composition in Polyolefins. IR4 is 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. It consists of two modules: Spectroscopic unit and Control unit. Spectroscopic Unit hosts the flow through cell and sensors. This unit must be connected in line with the analytical system.

A control and acquisition software has been developed to use the serial communication option in the IR4 Detector. Therefore, only one RS-232 standard cable is required to acquire the signals and to control the device.
Signals from measurement sensors and system control signals (temperature controls, vapor sensors) can be monitored and reviewed at any time as they are saved automatically in the computer. Signals corresponding to different injections are saved correspondingly by the software to facilitate subsequent calculations.
IR4 Control and Acquisition Software can be easily linked to Polymer Char’s GPC One Software modules, together with other detectors present within the same instrument.
IR4 Software also provides exportation capabilities in Excel format; therefore acquired data can be imported if needed into other software packages to perform the corresponding calculations.
