Atomic Absorption Spectrophotometer (AAS)

Area Linked to: 
Applied & Analytical Chemistry
Research Area: 
Chemical Analysis

Atomic absorption spectrometry (AAS) is an analytical technique that measures the concentrations of elements. Atomic absorption is so sensitive that it can measure down to parts per billion of a gram (ppb) in a sample. The technique makes use of the wavelengths of light specifically absorbed by an element. They correspond to the energies needed to promote electrons from one energy level to another higher energy level. AAS has many uses for measurement of metals for Clinical analysis: blood and urine; Environmental analysis: Water, drinks such as wine, beer and fruit drinks; Industry: Raw materials, toxic impurities; Mining: Ores, Minerals etc.
