Quality control of fuels (gasoline, diesel, kerosene) 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 fuels Metrohm offers a turnkey solution for the determination of multiple key parameters in gasoline, diesel and kerosene according to ASTM D6122. The measurement device consists of a DS2500

Liquid Near-infrared Analyzer with pre-calibration models based on a large collection of real product spectra. This solution enables fuel producers and fuel storage facilities, such as refineries, tank farms and testing labs, to save time and reduce the cost of their analysis.

Fuels such as gasoline, diesel and kerosene are Near Infrared Spectroscopy (NIRS) on the other hand widespread products in daily life.
