Inductively coupled plasma atomic emission spectrometry (ICP-AES) is a spectral analysis method based on inductively coupled plasma moment as excitation light source. ICP-AES detection is based on the unique emission spectrum of each element. The purpose of using inductively coupled plasmas is because the plasma can reach very high temperatures, which is conducive to the atoms or ions in the element to emit photons of characteristic wavelengths. Inductively coupled plasma atomic emission spectrometry is mainly used for qualitative and quantitative analysis of the elements in the sample, and can analyze more than 70 elements in the periodic table. The powerful quantitative function of ICP-AES is widely used in the analysis of sample elements, including nano, catalysis, energy, chemical, biological, geological, environmental protection, medicine, food, metallurgy, agriculture and so on.
