Principle
The instrument is based on the principle of atomic absorption spectroscopy (AAS). The sample is converted into ground state atomic vapor by flame or graphite furnace Atomizer, and the characteristic spectral lines emitted by the Hollow cathode lamp are selectively absorbed by the ground state atoms of the element to be measured when they pass through the atomic vapor. Quantitative analysis of the content of specific elements in the sample is achieved by measuring the degree of absorption of the characteristic spectral lines and comparing them with standard Linear dispersion. The instrument adopts a dual beam of light optical path design to compensate for light source fluctuations, and applies deuterium lamp and self-priming Background correction technology to eliminate background interference.
