| titleOfInvention | Ion trap mass spectrometry device and mass spectrometry method using the same |
| abstract | Various ions originating from the sample are captured in the ion trap, and then unnecessary ions other than target ions having a specific m/z are ejected from the ion trap ( S1 , S2 ). Then, the target ions captured in the ion trap are dissociated by hydrogen radical attachment and dissociation (HAD), and the resulting product ions are sequentially resonantly excited and discharged from the low m/z side until the m of the target ions is reached. Such an operation is repeated a plurality of times until /z (S3 to S7). MS/MS spectrum data is acquired by detecting ions ejected by resonance excitation with a detector, and data obtained by multiple resonance excitation and ejection are integrated to create a final MS/MS spectrum ( S5 , S8 ). The dissociation efficiency of the precursor ions of HAD is low, but the amount of product ions can be increased by repeating the dissociation operation by HAD and the resonance excitation discharge operation for the target ions generated by one ionization multiple times, and a high SN can be obtained. high-sensitivity MS/MS spectrum. |
