US09171706B1 Mass analysis device and mass analysis method
Mass analysis is performed on the same sample while changing the cooling gas supply rate to the ion trap, i.e. the gas pressure conditions, and the respective mass spectra are obtained.

Thus, between multiple mass spectra obtained while changing the gas pressure, if the mass difference between a peak for which signal intensity increased and a peak for which it decreased corresponds to the mass of a known modifier or an integer multiple thereof, it can be inferred that those peaks have the same basic structure and differ only in the number of modifiers.
