The study and Computer Simulation of Ion Trajectory in Inductively Coupled Plasma Mass spectrometer

The SIMION software package has been applied to simulate the ion trajectory in the input lens system of inductively coupled plasma mass spectrometer (ICPMS). The effect of input lens system position and different ion kineticenergy has been qualitatively eveluated. In order to collect the ions at high density area, a front electrode has been innovatively introduced to improve ICP/MS sensitivity.
