摘要
高功率密度激光电离飞行时间质谱法（Laser ionization time-of-flight mass spectrometry,LI-TOF-MS）是一种先进的固体元素直接分析法.与传统的固体分析方法相比,其样品前处理简单、分析速度快,而且消耗样品量少、无毒、绝对灵敏度高,已广泛应用于地质、环境等领域[1～3].与同类的固体直接分析法相比,激光电离飞行时间质谱法具有谱图干扰少,
An elemental imaging system was developed based on the high irradiance laser ionization time-of-flight mass spectrometry（LI-TOF-MS）,which could be applied to analyze all elements simultaneously and sensitively,including metals and non-metals.A stibnite sample was analyzed and elemental images of Sb,S,Si,Al,K,Ca,and Fe were subsequently acquired.Standardless semi-quantitation of detected elements on the stibnite surface was thus performed and the results indicate that the surface elemental imaging system asso-ciated with the LI-TOF-MS was a promising tool for elemental imaging of solid surface and standardless ele-mental semi-quantitation.
