Atomic Absorption Spectroscopy

---------------------------------------------------------------------------------------------

Atomic absorption spectroscopy (AAS) is process used by AEIS to accurately quantify many elements in alloys or materials.

Atomic absorption spectroscopy can be used to analyze the concentration of over 62 different metals in a solution .The concentrations of metals in the samples are also measured by it in the low range of mg/L.  Atomic Absorption Spectroscopy is a technique which measures the radiation absorbed by chemically unbound atoms. This is achieved by analyzing the transmitted energy relative to the incident energy at each frequency.  Atomic Absorption Spectroscopy could be used for different kind of analysis such as metallurgical, environmental, or coatings.
