| titleOfInvention | Tandem mass spectrometry analysis method performed in ion traps |
| abstract | The invention belongs to the technical field of mass analysis, in particular to a tandem mass spectrometry analysis method performed in ion traps. The method comprises ion selective isolation, collision induced dissociation and quality scanning analysis. Dipole excitation voltages with asymmetric wave shapes are imposed on a pair of electrodes to generate dipole direct voltages, so that isolated parent ions obtain energy to be excited, collided with neutral molecules in the ion traps and dissociated, and tandem mass spectrometry analysis is achieved. The tandem mass spectrometry analysis method performed in ion traps has the advantages that additional direct current power supplies are not needed, and the dipole direct voltages can be obtained only through the control of software, and experiment devices and methods can be simplified apparently. Simultaneously, the parent ions are subjected to a non-resonance excited dissociation mode under the action of the dipole direct voltages, and abundant ion fragment information can be given through the non-resonance excitation of collision and dissociation. |
