血液和尿液中元素ICP-MS分析研究进展

摘要

电感耦合等离子体质谱法(inductively coupled plasma-mass spectrometry,ICP-MS)是目前最常用的元素分析技术,具有灵敏度高、测量线性范围宽等优点,可进行血液、尿液中多元素同时分析.本文主要综述了ICP-MS的常见样品前处理方法(直接稀释法和湿法消解法)、对于质谱干扰和非质谱干扰的校正、影响分析结果准确度的主要因素,并对ICP-MS在法医毒物分析中的应用进行了展望.%Inductively coupled plasma-mass spectrometry (ICP-MS) is the most common technique for elements analysis at present. ICP-MS with high sensitivity and wide linear range can be applied to multi-elements analysis in blood and urine. This paper reviews the common means of sample pretreatment (direct dilution method and wet digestion method), the method for correction of mass spectral interference and non-interference, the main influence factors of analysis results, and provides an outlook of the application of ICP-MS in forensic toxicological analysis.
