摘要

综述目的:本文综述了电感耦合等离子体质谱(ICP-MS)和x射线荧光(XRF)在测定头发、指甲、血液、骨骼和组织等生物基质中金属和类金属的应用。它提供了这些方法的全面概述,详细说明了它们的技术局限性,应用范围,以及在实验室和现场设置中选择的实际考虑因素。通过检查每种方法的传统和新颖方面,本综述旨在指导研究人员和临床从业人员根据他们对灵敏度,精度,速度和样品制备的特定需求选择最合适的分析工具。最近的发现:最近的研究强调了ICP-MS和XRF技术的增强能力,使它们更能适应各种分析需求。ICP-MS以其在检测复杂生物样品(如等离子体或海水中的铅)中的超微量金属和类金属方面无与伦比的灵敏度和精度而闻名。XRF的进步包括更低的检出限和更短的样品制备时间,实现快速、非破坏性分析,是快速现场评估的理想选择。便携式XRF分析仪彻底改变了现场测试,在没有传统湿实验室限制的情况下提供可靠的数据。此外,结合ICP-MS和XRF特征的混合技术正在兴起,为环境监测、临床诊断和流行病学研究提供快速、精确的金属分析。将分析方法与具体的研究需求相匹配是至关重要的。ICP-MS是实验室中详细定量分析的金标准,而XRF在非破坏性,即时现场应用中表现出色。选择时应考虑样品的复杂性、灵敏度、速度和成本效益。集成ICP-MS和XRF为金属分析提供了一种通用的方法,改变了环境科学和医疗保健诊断的实践。随着这些技术的发展,它们有望扩大探测和了解金属和类金属在健康和环境中的作用的能力。

Ways to Measure Metals: From ICP-MS to XRF.

Purpose of review: This review explores the use of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and X-ray Fluorescence (XRF) for quantifying metals and metalloids in biological matrices such as hair, nails, blood, bone, and tissue. It provides a comprehensive overview of these methodologies, detailing their technological limitations, application scopes, and practical considerations for selection in both laboratory and field settings. By examining traditional and novel aspects of each method, this review aims to guide researchers and clinical practitioners in choosing the most suitable analytical tool based on their specific needs for sensitivity, precision, speed, and sample preparation.

Recent findings: Recent studies highlight enhanced capabilities of both ICP-MS and XRF technologies, making them more adaptable to various analytical needs. ICP-MS is renowned for its unmatched sensitivity and precision in detecting ultra-trace metals and metalloids in complex biological samples, such as lead in plasma or seawater. XRF advancements include lower detection limits and reduced sample preparation time, enabling rapid, non-destructive analyses, ideal for quick field assessments. Portable XRF analyzers have revolutionized on-the-spot testing, providing robust data without traditional wet-lab constraints. Moreover, hybrid techniques combining ICP-MS and XRF features are emerging, offering rapid and precise metal analysis for environmental monitoring, clinical diagnostics, and epidemiological studies. Matching analytical methods to specific research demands is critical. ICP-MS is the gold standard for detailed quantitative analysis in laboratories, while XRF excels in non-destructive, immediate field applications. Selection should consider sample complexity, sensitivity, speed, and cost-efficiency. Integrating ICP-MS and XRF offers a versatile approach to metals analysis, transforming practices in environmental science and healthcare diagnostics. As these technologies evolve, they are promising to expand capabilities in detecting and understanding the roles of metals and metalloids in health and the environment.
