The ICP-AES matrix matching method has been applied to determine the trace elements Ni,Be,Co,and Si in high conductivity copper,and the uncertainty of those elements has been analyzed.The results showed that the mass ratios of those elements were:Ni 2.13 mg/kg,Mg 0.088 mg/kg,Be 0 mg/kg,Co 0 mg/kg,Si 0.22 mg/kg and the main factors which determine the  uncertainty were the measurement repeatability and recovery rate.

Key words: ICP-AES, high conductivity copper, matrix matching, uncertainty
