| 摘要 |
The spectrometer has an electrostatic ion trap having an outer electrode (10) provided with an ion-repelling electric potential, and inner electrodes (21,22) provided with ion-attracting electric potentials. The outer electrode and the inner electrodes are arranged such that electric potential between the electrodes corresponds to a superposition of partial electric potentials of predetermined form comprising the values of Cartesian coordinates and several parameters. An independent claim is included for method of introduction of externally generated ions into electrostatic ion trap of mass spectrometer. |
