英文摘要	This work demonstrates, for the first time, the feasibility and capability of the high-precision simultaneous determination of Sm-147/Nd-144 and Nd-143/Nd-144 ratios in Sm-Nd mixtures using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) without Nd and Sm separation and without the use of costly enriched spikes. Mass discrimination was exponentially corrected by applying the natural constant of Nd-146/Nd-144 ratio as an internal standard, after correction of the isobaric interference of Sm-144 on Nd-144 using interference-free (SM)-S-147/(SM)-S-149 ratio for Sm mass fractionation, without assuming identical mass bias of Nd and Sm. The accuracy and precision of the present protocol, obtained from replicate analyses of various types of Sm-Nd mixtures encompassing a wide range of Sm/Nd (ca. 0.1-1.0) or Sm-147/Nd-144 ratios (ca. 0.06-0.62) was found to be comparable to the classic isotope dilution (ID) method. The present method is characterized by a higher sample throughput compared to the ID method, and shows great potential for the simultaneous determination of Sm-147/Nd-144 and Nd-143/Nd-144 ratios in real geological samples.
