Application of HPLC with Diode Array Detection in Tribology

A strategy for the analysis of engine oils is described based on the correlation between previously developed methods and HPLC. The areas of some chromatographic peaks of oil samples were linearly correlated to: covered kilometres, the kinematic viscosity, the amount of insoluble compounds in heptan...

Zusammenfassung:	A strategy for the analysis of engine oils is described based on the correlation between previously developed methods and HPLC. The areas of some chromatographic peaks of oil samples were linearly correlated to: covered kilometres, the kinematic viscosity, the amount of insoluble compounds in heptane, Conradson's carbonised residue, the number of alkalinity and the carbonyl number.
