3 Summary of method
The power supply excites periodically between the electrode and the surface of the sample, and the sample atoms are excited to emit characteristic spectrum. The YS/T464-20XX
spectral intensity is a function of element concentration. The computer automatically collects the excitation intensity value and calculates the element content.
