Quality control of Polymers (PE, PP, PET, Polyamide) Fast results with NIR pre-calibrations HIGHLIGHTS

− Chemical and physical parameters

− Based on real product spectra



− Can be used by non-specialists



Pre-calibrations expedite and simplify quality control of PE, PP, PET, and Polyamide Metrohm offers a turnkey solution for the determination of various quality parameters. The measurement device consists of a DS2500 Near-Infrared Analyzer with pre-calibration models based on a large collection of real product spectra. This solution enables polymer producers and polymer processors, such as compounders and injection molders, to save time and reduce the cost of their analyses while improving the quality of their product.
