    • 摘要: 同位素稀释-电感耦合等离子体质谱法(ID-ICP-MS)是一种高灵敏度的分析技术,近年来已广泛应用于地质、环境、生物及材料等领域中的痕量元素与同位素分析。为此,简要概述了ID-ICP-MS的基本原理,深入探讨了影响测量精密度和准确度的关键因素,并提出了相应的校正方法,重点综述了近十年来ID-ICP-MS及其联用技术的研究进展。对该技术在高通量、多元素分析领域的未来发展前景进行了展望,以期为提升ID-ICP-MS在复杂样品分析中的性能提供有价值的参考(引用文献77篇)。

       

      Abstract: Isotope dilution-inductively coupled plasma mass spectrometry (ID-ICP-MS) was a highly sensitive analytical technique. In recent years, it had been widely applied to the analysis of trace elements and isotopes in fields including geology, environment, biology and materials. Therefore, a brief overview of the basic principle of ID-ICP-MS was presented, the key factors that affected the precision and accuracy of measurements were thoroughly explored, and the corresponding correction methods were proposed. In particular, the research progress of ID-ICP-MS and its hyphenated techniques over the past decade were comprehensively reviewed. The future development prospects of this technology in the field of high-throughput and multi-element analysis were anticipated. The purpose of this work was to provide valuable references for improving the performance of ID-ICP-MS in the analysis of complex samples (77 ref. cited).
