The analysis of metallic elements is conducted based on the absorption of characteristic radiation by atomic vapor in its ground state. This method can sensitively and reliably determine trace or trace elements.

Elements are atomized by heating in a flame or a thermal decomposition graphite furnace, forming atomic vapor in its ground state. This vapor selectively absorbs the characteristic radiation emitted by a hollow cathode lamp. Within a certain concentration range, the absorption intensity is directly proportional to the content of the measured element in the test solution. The quantitative relationship can be described by the Lambert-Beer law, A = -log(I/Io) = -log(T) = KC, where I is the intensity of transmitted light, Io is the intensity of emitted light, T is the transmittance, L is the optical path length through the atomizer (which is fixed for each instrument), and C is the concentration of the sample being measured. Therefore, A = KC. The device used to measure the absorbance of atomic vapor through the resonance radiation of the element being measured is called an atomic absorption spectrophotometer. 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 elements and impurities, and has the two major advantages of high sensitivity and good selectivity. It is widely used in the analysis of trace elements in various gases, metal organic compounds, and metal alcohol salts.
