Atomic Absorption Spectroscopy

Atomic Absorption Spectroscopy is used for determining the composition of inorganic elements in a sample. AAS works on the principles of atomizing a sample and quantitatively  determining the concentration of atoms in the gas phase by measuring the intensity of light absorbed by them when they are irradiated with electromagnetic radiation. A key aspect of AAS is the method used to atomize the sample, which also affects the  sensitivity of the technique. Methods include flame, graphite furnace, electro-thermal, plasma furnace, and vapour-hydride atomization.
