Embodiment
[0050] The system can follow the figure 1 , figure 2 The structure shown in the diagram can be established, or other types of electrostatic field deflection can be used to make the ions end up in such as figure 1 Within the structure shown in the diagram; auxiliary confinement holes, ion lenses, electrostatic fields, ion detectors, etc. can be added anywhere in the system.
[0051] This embodiment takes figure 2 As an example to build the device, the process is as follows:
[0052] Purchase or develop core components such as quadrupoles, RF power supplies, and control systems. Adopt the r of Beijing Analytical Instrument Factory in this embodiment 0 =4mm, length 163mm hyperboloid quadrupole, QMH410-3 RF power supply produced by Inficon Company, and quadrupole control system. The quadrupole and its control system are insulated and suspended on the high voltage (about 9980V, adjustable) at the end of the deceleration lens, that is, the voltage reference of all circuits ...
