When a high-speed analyzer such as a quadrupole mass filter is united with an analyzer which requires a reaction time of 10 msec, such as an ion dissociation chamber of the ion trap type, a problem arises that an ion loss occurs due to a difference in analysis speed between the analyzers. A high-throughput analysis is intended to be achieved by eliminating this loss. A pre ion trap (4) is provided between a quadrupole filter (3) and an ion dissociation chamber (5), and ions are accumulated in the pre ion trap (4) while operations such as dissociation, isolation and ejection are being performed in the ion dissociation chamber (5). This configuration solves a problem with the ion dissociation chamber (5), which is a decrease in transmittance of the dissociation chamber (5), i.e., a decrease in throughput, and accordingly enables a high-throughput structural analysis on a measurement sample.
