Claim 0:
1. A mass spectrometer including an ionization unit, a mass separation unit, and a detection unit, the mass spectrometer comprising:
a first measurement control unit configured to control the ionization unit, the mass separation unit, and the detection unit so as to repeatedly execute a first measurement on a target sample while changing values of a plurality of parameters defined as device parameters;
a second measurement control unit configured to control the ionization unit, the mass separation unit, and the detection unit so as to set a value of each of the plurality of parameters to a predetermined reference value and execute 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 unit configured to correct 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 unit configured to determine the plurality of parameters using the measurement results corrected by the correction processing unit or acquire reference information for determining the plurality of parameters.
