| 摘 要： | 激光剥蚀电感耦合(LA-ICP-MS)等离子体以其高空间分辨率、高灵敏度、多元素同时测定并可提供同位素比值信息的检测能力在原位微区分析中已得到广泛应用。现从仪器的发展、基础研究等方面评述了近年来LA-ICP-MS微区分析的进展，重点介绍了与等离子体质谱(ICP-MS)联用的激光器(纳秒和飞秒激光器)的发展、校正方法、分馏效应及其在地球科学微量元素、同位素、包裹体分析中的应用。并简要地阐述了LA-ICP-MS分析技术存在的局限和发展趋势。 |

| Abstract: | Laser ablation inductively coupled plasma mass spectrometry(LA-ICP-MS) has been widely used in microanalysis because of its high sensitivity, low detection limits, the determination of major, minor and trace elements in solids, as well as isotope-ratio measurements. This review aims to summarize recent developments in LA-ICP-MS based on the instrumental and fundamental aspects. Emphasis is placed on the developments of laser ablation for sample introduction to ICP-MS(nanosecond and femtosecond laser), calibration strategies, fraction effects and its applications of minor element, isotope and melt and fluid inclusions in geosciences. At the same time, the limitations and future developments of LA-ICP-MS microanalysis techniques are also discussed. |
