ICP-AES is used for motor oil analysis. Analyzing used motor oil reveals a great deal about how the engine is operating. Parts that wear in the engine will deposit traces in the oil which can be detected with ICP-AES. ICP-AES analysis can help to determine whether parts are failing.
Inductively coupled plasma atomic emission spectrometer. Atomic emission spectroscopy (AES) is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample.
An inductively coupled plasma (ICP) for spectrometry is sustained in a torch that consists of three concentric tubes, usually made of quartz, although the inner tube (injector) can be sapphire if hydrofluoric acid is being used. The end of this torch is placed inside an induction coil supplied with a radio-frequency electric current.
ICP discharges are of relatively high electron density, on the order of 10 15 cm −3 [citation needed]. As a result, ICP discharges have wide applications wherever a high-density plasma (HDP) is needed. ICP-AES/ICP-OES, a type of atomic emission spectroscopy. ICP-MS, a type of mass spectrometry. ICP-RIE, a type of reactive-ion etching.

AAS is based on the absorption of light by free metallic ions that have been atomized from a sample. An alternative technique is atomic emission spectroscopy (AES). In analytical chemistry the technique is used for determining the concentration of a particular element (the analyte) in a sample to be analyzed.
Velmer A. Fassel (Ph.D. 1947)(deceased 1998), developed the inductively coupled plasma atomic emission spectroscopy (ICP-AES) analytical process, used for chemical analysis worldwide; former deputy director of the Ames Laboratory.
