A method for analyzing a structure of a substance of interest uses triple-quadrupole mass spectrometry (TQ-MS), and allows for acquisition of MSn information from data resulting from the TQ-MS measurement. The method includes (a) performing a measurement of triple quadrupole mass spectrometry with respect to the substance of interest while varying a value of CID energy; (b) at given values of CID energy, calculating percentages of precursor ion contents to a total ion content, and percentages of product ion contents to the total ion content; (c) extracting values of the percentages of product ion contents to the total ion content, wherein said values are values of the percentages of product ion contents at the respective values of CID energy; and (d) calculating sums of all combinations of the values of the percentages of product ion contents to the total ion content extracted in step (c).
