以高能量密度的激光作用于固体样品表面,产生高温等离子体,以飞行时间质谱计对其进行质谱分析,是近年来发展较快的分析手段之一,具有灵敏度高,分析速度快,分析范围广,样品损耗少,可进行微区分析等优点。本文介绍了本研究小组自行设计与研制的脉冲激光离子源飞行时间质谱计的原理、构造及其初步测试结果。 High-energy density laser effect on the solid sample surface, generating high-temperature plasma, time-of-flight mass spectrometry of its mass spectrometry analysis is one of the faster analysis in recent years, with high sensitivity, fast analysis, analysis of the scope Wide, less sample loss, micro-area analysis can be the advantages. This paper introduces the principle, structure and preliminary test results of pulsed laser ion source time-of-flight mass spectrometer designed and developed by our research team.
