How Does Atomic Absorption Spectroscopy Work?
Atomic Absorption Spectroscopy(AAS) is a quantitative analytical elemental technique that provides the total metal content of the sample and is almost independent of the molecular form of metal in the liquid sample. It analyzes the concentration of elements in a liquid sample based on energy absorbed from certain wavelengths of light. Alan Walsh, a Lancashire-born physicist was the one who worked on determining the small concentrations of metallic elements using spectroscopy. He got this idea in the 1950s while working in his garden. He worked on it for several years and finally convinced the manufacturers to use AAS for metallic determination. The first commercial AAS was launched in the 1960s and since then this technique has established a robust place in the field of analytical techniques. Principle of Atomic Absorption Spectroscopy The AAS technique is based on the absorption of energy by ground-state atoms in the gaseous state. It states […]
