Atomic Emission Spectroscopy

Atomic Emission Spectroscopy

Atomic Emission Spectroscopy, or AES, is a method for determining the elemental composition of metals and alloys. AES analysis uses a “spark” process, which involves applying an electrical charge in an Argon atmosphere to produce a plasma, vaporizing a small amount of material. Once the “spark'' occurs, a chemical fingerprint is created based on wavelengths of light. The spectrometer measures the light to allow our (engineers – experts - technicians) to determine the elemental composition of the sample. The spectrometer produces an elemental composition translated to percentages of the constituent elements.
