In order to accurately determine major elements (Cu, Sn, Zn and Pb) in milligram amounts of bronze reference samples, an application of ICP-AES using scandium as an internal standard element was investigated. The correlation coefficient of each major element to scandium was above 0.93 and the repeatable precision in measuring the emission intensity ratio of each major element to scandium was 0.10∼0.45% (RSD, %, n=25), which corresponded to 1/3∼1/5 times that obtained without an internal standard. In an analysis with a 10mg amount of the sample, the relative variances for 4 major elements {Relative variance (%)=[(Mfound-Mcert)/Mcert]×100, where Mfound and Mcert are the found and certified values, respectively.} were 0∼−1.4%, except for Pb. On the other hand, those obtained from an analysis with a 5mg or a 2mg amount of sample were −0.8∼−6.3%.
