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

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。

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 Ar ionization 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.
