摘要： 在自行研制的LI-TOF-MS[6]的基础上, 发展了新的LI-TOF-MS固体元素成像分析系统, 并在优化了的实验条件下, 对辉锑矿矿石样品(主要成分为Sb2S3)的表面进行了元素分析, 得到了Sb, S, Si, Al, K, Ca和Fe等元素的表面成像图. 矿石表面或截面的元素成像(或分布)对矿石乃至矿床的形成过程及分布特征等的研究具有很大的参考价值, 在地质学上具有重要意义.

Abstract: 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 associated with the LI-TOF-MS was a promising tool for elemental imaging of solid surface and standardless elemental semi-quantitation.
