摘要
In a mass spectrometer a focusing ion lens system effectively separates charged from neutral particles by forming a potential well along the axis from the ionizing region to the mass analyzer by the use of a gridded lens system. The grids by the use of a high-low voltage combination form the potential well while at the same time allowing nonselected neutral particles to pass through the grid. Thus, the system is very effective for relatively high pressure ionizing regions where a large amount of neutral particles are generated.
