In this study, the uncertainty of the determination of trace uranium by isotope dilution high resolution inductively coupled plasma mass spectrometry (ID-ICPMS) had been evaluated.This evaluation illustrated the contribution of uncertainty of the blend isotope ratios was large. So the accuracy of determination of the isotope ratios is the major factor for improving the accuracy of the method.展开更多
