atomic absorption spectrometer


A device that uses the resonance radiation of an element to be tested and whose absorbance is measured by its atomic vapor is called an atomic absorption spectrophotometer. It has single-beam, double-beam, double-channel, multi-channel and other structural forms. Its basic structure includes a light source, an atomizer, an optical system, and a detection system. 


It is mainly used for the analysis of trace element impurities, and has two main advantages: high sensitivity and good selectivity. Widely used in the analysis of trace elements in various gases, metal organic compounds, metal alkoxides. However, the determination of each element requires a corresponding hollow cathode lamp, which is inconvenient for the inspection work.
