Atomic Absorption Spectroscopy (AAS) Technology

Atomic absorption spectroscopy (AAS), also known as atomic spectrophotometry, is based on the absorption of the characteristic spectral line by the ground state atomic vapor of the element to be measured. The technology is used to analyze the measured elements qualitatively and quantitatively according to the characteristic of the characteristic spectral lines and the degree of attenuation of the spectral lines. Atomic absorption spectrometry has the advantages of low detection limit, high sensitivity, good analytical accuracy and fast analytical speed, and can be used to determine up to 70 kinds of elements, including metallic elements, non-metallic elements and organic compounds.
