Analysis of elemental impurities in diesel by HR ICP-OES according to ASTM D7771-16

Diesel is a mixture of kerosene and different middle distillate fractions, which are produced by fractionation of crude oil. Further components of diesel products may be a certain portion of biodiesel (up to 7%) and additives (ppm concentration range) to adjust properties such as ignitability, cetane number, lubricity, acidity and stability. Elemental impurities in diesel products contribute to properties like shelf life, wear of engine components and exhaust treatment devices as well as emission levels of environmental pollutants and particulate matter.
