Abstract: This paper takes LEEMAN Prodigy and other Inductively Coupled Plasma Atomic Emission Spectrometer(ICP-AES)as examples,introducing the working principle of ICP-AES and instrument structure. On the basis of laboratory instrument management experience for many years,this paper summarizes utilization environment and conditions of this instrument,and puts forward concrete methods on equipment maintenance. This paper aims to provide the related suggestions for people who are engaged in instrument management on Inductively Coupled Plasma Atomic Emission Spectrometer(ICP-AES).
