单极质谱仪中离子运动轨迹的计算机模拟

Computer Simulation of Ion Trajectories in Monopole Mass Spectrometer

利用一个自编的模拟单极质谱仪中离子运动轨迹的BASIC程序,在IBM-PC/XT微机上分析了工作点、初始相位和单极场的电长度对离子轨迹以及单极场入口处离子初始状态的约束条件的影响.

This paper presents a BASIC program for simulating ion trajectories in monopolc mass spectrometer. The effects of the working points, initial phase and electric length of the monopole field on ion trajectories and restraint conditions of the initial states of ions at the entrance of the monopole field are analyzed using this program.
