Atomic Absorption Spectrometers

Atomic absorption spectrometry is a technique exploiting the fact that atoms at ground state may absorb the radiation of characteristic wavelength. As is known, the atoms are usually at ground state. For each element, the amount of energy required for an atom to transit from ground state to excited state is specific, and in general, is called characteristic wavelength. The Atomic absorption spectrometry typically makes use of hollow cathode lamp as the light source to emit the characteristic wavelength of a particular element. When the light passes through the atomic vapor, it is absorbed by the vapor. The concentration of the element can then be determined through the calculation of the absorption rate.
