<P>PROBLEM TO BE SOLVED: To provide a method for accurately estimating the number of carbon atoms in fragment ion of an organic compound having a great carbon atom content. <P>SOLUTION: An analysis method includes the steps of: performing mass analysis on product ion produced from first or second precursor ion of which the mass-to-charge ratio is greater by 1 than that of ion obtained by ionizing a first organic compound or ionizing a second organic compound that is obtained by changing the number of carbon atoms in the first organic compound; determining a ratio of heights of peaks between the first fragment ion which is obtained by performing mass analysis on product ion produced from the first precursor ion, and the second fragment ion of which the mass-to-charge ratio is smaller by 1 than the first fragment ion; and determining a ratio of heights of peaks between fragment ion, corresponding to the first fragment ion, obtained by performing mass analysis on product ion produced from the second precursor ion, and fragment ion corresponding to the second fragment ion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
