<p>An analysis method which comprises: the step of analyzing by mass spectrometry a product ion generated from a first precursor ion, which has a mass-to-charge ratio larger by 1 than that of an ion formed by ionizing a first organic compound; the step of analyzing by mass spectrometry a product ion generated from a second precursor ion, which has a mass-to-charge ratio larger by 1 than that of an ion formed by ionizing a second organic compound, which is obtained by changing the number of the carbon atoms of the first organic compound; the step of determining the ratio of the peak height for a first fragment ion to the peak height for a second fragment ion, which has a mass-to-charge ratio smaller by 1 than that of the first fragment ion, the peak heights being obtained by the analysis by mass spectrometry of the product ion generated from the first precursor ion; and the step of determining the ratio of the peak height for a fragment ion corresponding to the first fragment ion to the peak height for a fragment ion corresponding to the second fragment ion, the peak heights being obtained by the analysis by mass spectrometry of the product ion generated from the second precursor ion.</p> |
