Copper-chromium-indium(Cu-Cr-In)alloy is a kind of high strength and high conductivity alloy material with excellent mechanical properties.The method for the determination of indium in Cu-Cr-In alloy by inductively coupled plasma optical emission spectrometry was established.The operation parameters of the instrument were optimized and the interference of matrix was investigated to determine the analytical spectral line at 230.606 nm and establish the standard curve by matrix matching method.Finally,the pre...
