Atomic absorption spectroscopy (AAS) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic absorption spectroscopy is based on absorption of light by free metallic ions.
With the increasing emphasis on quality work, quality control is more from empirical control to parameter control, and the use of atomic absorption spectrophotometers has become increasingly widespread.
Atomic absorption spectrometers are precision special equipment that requires regular commissioning and maintenance. According to the operation regulations and precautions, combined with practical experience, several methods of instrument debugging, instrument maintenance and maintenance during the use of atomic absorption spectrometer are discussed, so that the instrument analysis can achieve the best results at any time.
