摘要
目前国内外的飞行时间质谱计,大多采用双电场加速的方式改善其质谱分辨率。本文通过较详尽的计算,讨论了双电场飞行时间质谱计中各参数对质谱分辨率的影响及其选择的方向,为飞行时间质谱计的设计与改进提供了依据。本文还介绍了在此基础上设计与建立的脉冲激光离子源飞行时间质谱计。
Most of the time-of-flight mass spectrometers in the world are still based on Willy-Mclaren double-field design. Choise of the parameters, however, basically depends on experiences. In this pepar, we try to solve this problem by detailed calculations and discussions, and to provide a theoretical background for the designs and improvments of time-of-flight mass spectrometers. Based on these considerations, a pulsed laser probe time-of-flight mass spectrometer has been built. The configuration and the preliminary experiment will also be brcifly introduced in this paper.
