| 摘要 |
The present invention relates to analysis of organic compounds using an ion trap mass spectrometer. Substantially, the method of the present invention comprises steps of isolating ions of a wide mass range including isotope peaks, performing CID (Collision Induced Dissociation) on a plurality of ions simultaneously to produce daughter ions, obtaining the mass spectrum of the daughter ions, accumulating ionic currents of isotope peaks of the obtained daughter ions, comparing the result by the isotope pattern of the daughter ions, and evaluating the result of analysis.
