Determination of additive elements, wearing metals and contaminants in used lubricating oils by Inductively Coupled Plasma (ICP) Atomic Emission Spectrometry. This test provides a rapid screening of used oil for wearing indications.

Inductively Coupled Plasma Atomic Emission Spectrometers (ICP) can measure 23 elements simultaneously down to 0.1 parts per million. High concentrations of particular elements can indicate excessive engine wear or the presence of contaminants. Since the wearing rate of every engine is different, each engine is treated individually; And since metals have unique elemental concentrations, it is possible to predict the likelihood of bearing failure and component wear e.g metallic oil seals, oil pumps. Levels of those elements characteristic of oil additives are useful for confirmation of the oil grade in use, moreover, they may indicate contamination with fuel, oil, water, or incorrect oil type.
