我们使用多接收器电感耦合等离子体质谱 (MC-ICP-MS) 重新评估了 Sr 同位素分析过程中双电荷重稀土元素的干扰。测量一系列标准参考材料 SRM 987、稀土元素和从岩石标准材料中分离的 Sr 的混合溶液,以评估同量异位素干扰对 Sr 同位素 MC-ICP-MS 分析的影响。样品溶解后,在 MC-ICP-MS 测量之前,采用传统的阳离子交换色谱法对岩石标准物质进行 Sr 纯化。已经证明,如果使用 Er 和 Yb 的自然丰度来校正 Sr 上的双电荷离子干扰,则会导致过度校正。相比之下,使用测量的双电荷离子比率可以准确且精确地校正同量异位素干扰。从镁铁质(玄武岩)到长英质(花岗岩)硅酸盐岩石的几种经过认证的参考材料的分析结果证实了这一发现。值得注意的是,由于Er更容易形成双电荷离子,因此它在干扰源方面优于Yb双电荷离子。
We re-evaluate the interference of doubly charged heavy rare earth elements during Sr isotopic analysis using multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). A series of mixed solutions of standard reference material SRM 987, rare earth elements, and Sr separated from rock reference materials are measured to assess the influence of isobaric interferences on the MC-ICP-MS analysis of Sr isotopes. After sample dissolution, conventional cation-exchange chromatography is employed for Sr purification of rock reference materials prior to MC-ICP-MS measurement. It has been demonstrated that if the natural abundances of Er and Yb are used to correct for doubly charged ion interferences on Sr, an overcorrection results. In contrast, the use of measured doubly charged ion ratios results in an accurate and precise correction of isobaric interference. This finding is confirmed by analytical results for several certified reference materials from mafic (basaltic) to felsic (granitic) silicate rocks. It is noteworthy that, because Er is more prone to doubly charged ion formation, it dominates over Yb doubly charged ions as an interference source.
