This Application Note describes the determination of various indices (mainly with ASTM and ISO conformance) for the characterization of kerosene as aviation turbine fuel using near-infrared spectroscopy. The following parameters were determined with the aid of an NIRS XDS Process Analyzer: degree of density in accordance with the American Petroleum Institute (API), aromatics content, Cetane Index, distillation characteristics pursuant to ASTM D86, flash point, freezing point, viscosity and hydrogen content. All of these parameters are determined quickly and easily with just a single measurement.
