Elemental analysis is used
to evaluate and quantify wear metal elements, additive elements,
contamination elements and trace metal elements. Wear metals are analyzed
to pinpoint problem areas through trend analysis. By analyzing the
additive elements the oil classification of a sample can be verified, i.e.
hydraulic oil, transmission fluid, or engine oil. Test results are
obtained by I.C.P. (Inductive Coupling Plasma)
atomic emission spectrometer and is reported in terms of parts per million
(ppm) for elemental metals from 0.1 to 8 micrometers (um) by
ASTM-D-5185. Contamination elements
are reviewed to determine lubricant serviceability and to pinpoint causes
of problems indicated by other test results.
Following elements are the typical twenty-(21) sources of the elements
analyzed and their function in a component:
