| 英文摘要 | Thermal ionization mass spectrometry (TIMS) offers the excellent precision and accuracy of the Stand Nd isotopic ratio analysis for geological samples, but this method is labour intensive, expensive and time-consuming. In this study, a new analytical protocol by TIMS is presented that aims at improving analytical efficiency and cutting down experimental cost. Using the single-step cation exchange resin technique, mixed Sr and rare earth elements (REEs) fractions were separated from matrix and evaporated to dryness. Afterwards, mixed Sr + REEs fractions were dissolved and loaded onto the same Re filament using 1 mu L of 2 M HCl. Then, Sr and Nd were sequentially measured without venting using TIMS. In contrast to conventional TIMS methods, the merits of this analytical protocol are its cost- and timesaving adaptations. The applicability of our method is evaluated by replicated measurements of Sr-87/Sr-86 and Nd-143/Nd-144 for nine international silicate rock reference materials, spanning a wide range of bulk compositions. The typical internal precision in this study is ca. 0.001% (RSE) for Sr-87/Sr-86 and Nd-143/Nd-144; the analytical results obtained for these standard rocks show a good agreement with reported values, indicating the effectiveness of the proposed method.
