In this process, a solid metal sample is sparked (vaporized) in an argon atmosphere. The light emitted by the excited atoms is separated into specific wavelengths, and the intensity of these wavelengths is measured to determine the concentration of various elements. To maintain accuracy, the spectrometer must be regularly
