Accurate determination of elements in various kinds of samples is essential for many areas, including environmental science, medicine, as well as industry. Inductively coupled plasma mass spectrometry (ICP-MS) is a powerful tool enabling multi-elemental analysis of numerous matrices with high sensitivity and good precision. Various calibration approaches can be used to perform accurate quantitative measurements by ICP-MS. They include the use of pure standards, matrix-matched standards, or relevant certified reference materials, assuring traceability of the reported results. This review critically evaluates the advantages and limitations of different calibration approaches, which are used in quantitative analyses by ICP-MS. Examples of such analyses are provided.This article is part of the themed issue 'Quantitative mass spectrometry'.
准确测定各类样品中的元素对于许多领域至关重要,包括环境科学、医学以及工业。电感耦合等离子体质谱法(ICP-MS)是一种强大的工具,能够对众多基质进行多元素分析,具有高灵敏度和良好的精密度。可采用各种校准方法通过ICP-MS进行准确的定量测量。这些方法包括使用纯标准品、基质匹配标准品或相关的有证标准物质,以确保所报告结果的可追溯性。本综述批判性地评估了用于ICP-MS定量分析的不同校准方法的优缺点,并提供了此类分析的示例。本文是主题为“定量质谱”的特刊的一部分。
