高分辨率高灵敏度飞行时间质谱仪

Time of Flight Mass Spectrometer with High Mass Resolving Power and High Sensitivity

本文讨论了提高飞行时间质谱仪的分辨率和灵敏度的基本问题，给出了仪器的结构设计。实验表明，其分辨率Ｒ＞２５００，灵敏度为３０Ａ／Ｐａ。

The methods to improving the mass resolving power and sensitivity of TOFMS are discussed and a design of the instrument is proposed.The experiments results of R>2500 and S>30A/Pa have been shown.
