ABSTRACT:
An ion mass spectrometer comprising an ionization source for generating ions, a linear trap region for accumulation and dissociation of ions, and a time-of-flight mass spectrometer for mass spectroscopy of ions based on the flying time, and having a collision damping region introduced with a buffer gas for reducing the kinetic energy of ions ejected from the linear trap region and converting the ion packet into continuous beam and provided with plural electrodes for generating multipole electric fields in the inside between the linear trap region and the time-of-flight mass spectrometer, and having an ion transmission control mechanism for allowing or inhibiting incidence of ion from the linear trap region to the collision damping region between the linear trap region and the collision damping region.
