Claim 7:
8. A mass spectrometry method using a mass spectrometer including an ionization unit, a mass separation unit, and a detection unit, the mass spectrometry method comprising:
a first measurement step of repeatedly executing a first measurement on a target sample while changing values of a plurality of parameters defined as device parameters;
a second measurement step of setting a value of each of the plurality of parameters to a predetermined reference value and executing a second measurement on the target sample at not less than two time points before, after, or in a middle of repetition of the first measurement;
a correction processing step of correcting results of the first measurements by using results of the second measurements executed at not less than two time points; and
a device parameter-related information acquisition step of determining the plurality of parameters using the measurement result corrected in the correction processing step or acquiring reference information for determining the plurality of parameters.
