Quadrupole ion trap mass spectrometer having two axial modulation excitation input frequencies and method of parent and neural loss scanning |
摘要 |
There is described a method of operating an ion trap mass spectrometer. The method is carried out by trapping ions of selected masses in a three-dimensional field and then generating at least two fields in said trap having different frequencies to excite multiple trapped ions.
