摘要

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.
