Atomic emission spectroscopy
Atomic emission spectroscopy (AES) is a method of chemical analysis that uses the intensity of light emitted from a flameplasmaarc, or spark at a particular wavelength to determine the quantity of an element in a sample. The wavelength of the atomic spectral line gives the identity of the element while the intensity of the emitted light is proportional to the number of atoms of the element.
