摘　　要：激光剥蚀-等离子体质谱(LA-ICPMS)已成为地球化学、宇宙化学和环境研究领域元素和同位素原位分析最重要的技术之一。文章介绍了多种类型的质谱仪及其使用的激光器。用途最广的LA-ICPMS仪器之一是单接收器扇形磁场质谱仪,配有Nd:YAG激光剥蚀系统(激光波长分为193 nm和213 nm两种),MPI Mainz实验室使用的就是这套系统,文章对此作一详细介绍。文中阐述了数据优化技术及其多种校正过程;介绍LA-ICPMS在痕量元素和同位素分析领域的一些应用,包括参考物质的研制,Hawaiian玄武岩、Martian陨石、生物骨针和珊瑚虫中痕量元素分析及熔融包裹体和富钙-铝碳质球粒陨石中的铅和锶同位素测量。Laser ablation （LA）-inductively coupled plasma-mass spectrometry （ICP-MS） has become one of the most important methods for in situ trace elemental and isotopic analysis in geochemistry, cosmochemistry and environmental research. For these purposes, different kinds of mass spectrometers and lasers are used, which are presented in this paper. One of the most useful LA-ICPMS instruments is the combination of a single-collector sector field mass spectrometer with Nd： YAG laser ablation systems （193 nm and 213 nm wavelengths, respectively）. This design used in the MPI Mainz laboratory is described in detail in this paper. Data optimization techniques including diverse correction procedures are also discussed. To demonstrate the power of LA-ICPMS, several applications of trace elemental and isotopic analysis are presented, such as investigations of reference materials, trace element analysis in Hawaiian basalts, Martian meteorites, biological spicules and corals, as well as Pb and Sr isotope measurements of melt inclusions and Ca-Al rich inclusions of carbonaceous ehondrites.
