<P>PROBLEM TO BE SOLVED: To provide a mass analyzing system capable of determining having high valence number is detected because the peak interval (1/valence number) of an isotope peak becomes narrow in the ion having the high valence number and it is difficult to determine the valence number in the present mass analyzing system. Ž<P>SOLUTION: The mass analyzing system is characterized in that a plurality of the ion kinds of the same compounds having the same mass and different valence numbers are predetermined from a mass analyzing spectrum, the least common multiple is calculated within the range of tolerance predetermined with respect to the M/Z value of a plurality of the ion kinds, and the masses of a plurality of the compounds and the valence numbers of the respective ion kinds are estimated. As a result, the enhancement of data analyzing precision after the completion of analysis and the reduction of the load of a tester are expected. Further, by using a tandem mass analyzing method, the measurement of a sample containing a plurality of components in a mixed state or the avoidance of dublicate analysis to the same component different in valence number becomes possible.
