1. An analytical instrument, comprising:

  • an ionization means for ionizing a mixture of a target sample and a specific compound added thereto;

    a means for performing mass analysis on resulting ions; and

    a data processor that determines the concentration of a target compound contained in the target sample,wherein the data processor includes a database that stores dependence of signal intensity on the concentration of a specific matrix component for each of the target compound and the addition compound, and the data processor calculates, by using the database, the concentration of the target compound from a signal derived from the target compound and a signal derived from the addition compound, each signal obtained by the mass analysis means.
