Due to the development of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) around 25 years ago, the isotopes of a large range of elements (masses from Li to U) are now analyzed with high enough precision and accuracy to resolve subtle natural variations. These so-called 'non-traditional stable isotope systems' opened many new research avenues and are applied at an increasing rate in research and industry projects and in a broad range of different disciplines, including archeology, biology, physics, cosmochemistry and geology. Here, we briefly summarize the most basic concepts of MC-ICP-MS, introduce new technical developments and address important points on how to acquire accurate high-precision isotope measurements of non-traditional stable isotopes.
大约25年前，由于多接收电感耦合等离子体质谱仪（MC-ICP-MS）的发展，现在可以对大量元素（质量数从锂到铀）的同位素进行分析，其精度和准确度足以分辨细微的自然变化。这些所谓的“非传统稳定同位素体系”开辟了许多新的研究途径，并在研究和工业项目以及包括考古学、生物学、物理学、宇宙化学和地质学在内的广泛不同学科中以越来越高的频率得到应用。在此，我们简要总结MC-ICP-MS的最基本概念，介绍新的技术发展，并阐述关于如何获得非传统稳定同位素的准确高精度同位素测量的要点。
