Atomic Emission Spectroscopy

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. The wavelength of the atomic spectral line in the emission spectrum indicates the element's identity, while the intensity of emitted light is proportional to the number of atoms of the element.
