For example - salt water contamination would cause as an increase in Chlorine, Sodium and Magnesium and some lesser elements. There are also many contaminants that can enter an oil compartment and cause damage, and elemental analysis can detect these before significant harm is done. Rapid changes in the rate of wear can be an early indication of a fault developing or of abnormal conditions that are decreasing the life expectancy of the component. These wear metals should accumulate at a slow, steady rate. Each oil type has a unique signature of elements from the oil additives which are present in the new oil.ĭuring use the oil accumulates microscopic particles of wear metals which are detected as elements. These machines provide us with the elemental composition of the oil in mg/kg (parts per million). Elemental analysis is performed using ICP (Inductively Coupled Plasma) or in some cases XRF (X-Ray Fluorescence) spectroscopy.
