Abstract
After various ions of sample origin have been captured within an ion trap, unnecessary ions other than a target ion having a specific m/z are ejected from the ion trap (S, S). Subsequently, an operation for dissociating the target ion within the ion trap by hydrogen radical dissociation (HAD), and an operation for sequentially ejecting the thereby generated product ions by resonance excitation from the low m/z side to a point located immediately before the m/z of the target ion, are repeated multiple times (S-S). The ions ejected by resonance excitation are detected with a detector to acquire MS/MS spectrum data, and the data obtained by performing the ejection by resonance excitation multiple times are accumulated to create the final MS/MS spectrum (S, S).
