| Abstract: | The influences of three instrumental parameters of ICP-MS spectrometer(radio frequenceypower, nebulization gas flowrate and ion lens voltage)on signal intensity and productivity of a few kinds ofions formed from 15 rare earth elements in the plasma(single element ions RE+,oxide ions REO+,hydroxideions REOH+ and hydride ions REH+)have been investigated. The relationship betWeen the productivity rate ofthese ions and properties of relevant RE element has been explored. The results use for selecting instrumentalparameters for determination of 14 trace rare earth impurities in high-purity single rare earth samples by ICPMS. |
