It is suitable for quick and accurate sample analysis of approximate 70 trace and normal elements in fields and sectors such as geology, metallurgy, rare-earth and magnetic materials, environment, medicine and health, biology, marine, petroleum, chemical new materials, nuclear industry, agriculture, food inspection, water quality, etc.The ICP-OES is designed for quantitative analysis of metallic and non-metallic elements in liquid samples (including solid materials that can be transformed into solutions after chemical treatment). Sample solution is pipedinto a plasma torch in the form of aerosol, and then the sample gives off light of characteristic wavelengths depending onelements contained in it after it is evaporated and excited. After the beam is split bythe beam splitting system, the intensity of spectral lines is accepted by a photoelectric element, and transformed into electric signals and then recorded. The concentration of the elementsis determined according to the relationships between the element concentration andtheintensity of spectral lines.
