Atomic Spectroscopy Overview

Schematic of a basic atomic absorption spectrometer composed of a light source, atomizer, monochromator and detector.

Atomic spectroscopy uses the electromagnetic radiation or mass spectrum of a sample to determine elemental composition. The wavelength of energy absorbed or emitted by atoms is characteristic to each element and can be used for element identification and quantification.  

Analytical techniques based on atomic spectroscopy are widely used in environmental chemistry, geology and soil science, mining and metallurgy, food sciences, and medicine.
