| titleOfInvention | Tandem mass spectrometer and program for the same |
| abstract | When data is obtained by mass spectrometry, the mass spectrum analysis unit (32) immediately determines the signal intensity on the mass spectrum for each small m / z range obtained by dividing the entire m / z range to be measured by a predetermined m / z width. Find the integrated value of Then, only the m / z small range whose signal intensity integrated value is equal to or more than a predetermined threshold value is selected as a target of MS / MS analysis. The MS / MS analysis control unit (41) performs MS / MS analysis using, as precursor ions, ions whose m / z is included in the m / z small range for each selected m / z small range. Thus, after repeatedly executing the measurement cycle including one mass analysis and one or more MS / MS analysis, the identification processing unit (35) is identical based on the retention time of the peak in the extracted ion chromatogram of each product ion The component-derived ions are sorted to identify the component. This makes it possible to reduce the number of times of MS / MS analysis and shorten the time of one measurement cycle while collecting information on product ions derived from ions observed in the mass spectrum as much as possible. |
