This article serves three purposes:

A high-voltage electrical spark is discharged onto the surface of a prepared aluminum sample. The intense energy from the spark excites the atoms within the metal. As these excited atoms return to their normal state, they emit light at specific, characteristic wavelengths. An optical spectrometer captures this light, and by measuring the intensity of the specific wavelengths, the instrument can precisely determine the concentration of various elements within the sample. This process requires an argon atmosphere, which prevents oxidation and ensures a stable plasma for accurate results. : Indicates a subsequent revision or amendment made
