Atomic Absorption Spectrometry with Electrothermal Vaporization (GF-AAS)

This analytical technique is used for the determination of single elements in a solution, based on the absorption of electromagnetic radiation by free atoms in the gaseous state. Analytes are first atomized so that their characteristic wavelengths are emitted and recorded. The atomization of the sample is carried out by supplying energy provided by a GF-AAS graphite chamber. It is a monoelemental technique that requires solution prior to analysis in the case of solid samples. This technique has many applications, including the determination of metals in samples of water, rocks, soil, sediments, glass, alloys, plants, blood or biological tissues.
