PROBLEM TO BE SOLVED: To provide a mass spectrometry system which allows for acquisition of mass spectrum with higher resolution for ions of higher mass number.SOLUTION: In a mass spectrometry system, a control unit 8 controls a mass analyzer 4 so that the DC voltage U, the high frequency voltage amplitude value V, and the high frequency voltage frequency f, being applied to a quadrupole electrode 13, are increased as the mass to charge ratio m/z of analyzed ions increases. Since the ion frequency of ions having a higher mass number increases more when passing through the mass analyzer 4, mass spectrum of higher resolution can be acquired. |
