Atomic spectrometry, sometimes called atomic spectroscopy or optical atomic spectrometry, is a set of tools for analytical chemistry that involves the measurement of light produced by the interaction of photons with the atoms of chemical elements. It is based on the properties of electrons at different energy levels within electrons, and the properties that cause light, of a charateristic wavelength, to be absorbed in moving an electron to a more energetic level, or to be emitted when electrons decay to a less energetic energy level.
There are three broad types of atomic spectrometry:[1]
- Atomic absorption spectrometry
- Atomic emission spectrometry
- Atomic fluorescence spectrometry
