| 摘 要： | This paper describes the quantitative determination of rare-earth elements cerium, dysprosium andnon-rare-earth element copper, lead and the homogeneity examination of these four elements in yttrium oxidereference material by isotope dilution spark source mass spectrometry (ID-SSMS). The sensitivity of the meth-od is l0~(-5)～10~(-7%). The precision is better than 6%. The accuracy is better than 5%. The interferences of thespectra and the optimum amount of the spike added to the sample are discussed. The choice of the conductingmaterial for the sample electrodes is studied.
