摘要

电感耦合等离子体质谱(ICP-MS)是一种越来越多地被用于商业实验室和工业分析具有复杂基质的样品的技术，如海水、废水、含盐地下水和其他高盐样品。这些实验室通常选择ICP-MS，因为其快速、多元素的能力和高样品通量，但时间和成本的压力意味着实验室几乎没有时间进行样品制备和方法开发。时间和成本压力可能会导致性能和操作问题，因为针对最高灵敏度进行优化的ICP-MS仪器可能没有足够的基质容忍度来分析高盐样品。在本文中，我们描述了一种优化等离子体鲁棒性和干扰控制的方法，使现代ICP-MS能够对未稀释海水中的关键微量元素进行简单、准确和常规的分析。

ICP-MS Configuration and Optimization for Successful Routine Analysis of Undiluted Seawater

Inductively coupled plasma–mass spectrometry (ICP-MS) is a technique increasingly being used in commercial laboratories and industries that analyze samples with complex matrices, such as seawater, wastewater, saline groundwater, and other high salt samples. These laboratories often choose ICP-MS for its fast, multielement capability and high sample throughput, but time and cost pressures mean that laboratories have little time for sample preparation and method development. The time and cost pressures can lead to performance and operational issues because an ICP-MS instrument optimized for the highest sensitivity may not have the sufficient matrix tolerance to analyze high salt samples. In this article, we describe a method to optimize plasma robustness and interference control that enables a modern ICP-MS to perform simple, accurate, and routine analysis of critical trace elements in undiluted seawater.
