Metal emission spectra
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 gives the identity of the element while the intensity of the emitted light is proportional to the number of Web21 jul. 2024 · Atomic emission spectroscopy (AES) is an analytical technique used for the quantification of metal atoms by measuring the intensity of light emitted by the atoms in excited states. When an excited atom returns to the ground level, it emits radiation in a discrete wavelength. Atomic emission spectroscopy involves both excitation …
