飞行时间型质量分析器(TOFMS)的研制及应用

Development and Application of The-of-Flight Mass Spectrometer

摘要: 自行研制了电子碰撞离子化的飞行时间型质量分析器(TOFMS),用于物质的化学分析。用研制的TOFMS测量了Ar离子化的飞行时间谱和离子的部分电离截面积比与碰撞电子能量的依赖关系,将它与Stepshan等人的实验结果进行了比较。

Abstract: The time-of-flight mass spectrometer(TOFMS)with electron collision ionization for chemical analysis of materials is developed by ourselves.The the-of-flightspectrum of Arionization and the dependence of partial ionization cross section ratio on electron collision energy are measured with the developed TOFMS.The experimental results are compared with that of Stephan et al.
