Abstract
A mass spectrometric device of the present invention includes a quadrupole filter () located upstream of a quadrupole ion trap () and configured to transmit ions in a predetermined filter range, and determines the filter range of the quadrupole filter () such that accumulation time for the ions in the quadrupole ion trap () is maximized. The accumulation time for the ions is determined based on mass spectrometry data information. With this configuration, the present invention produces advantageous effects of improving analysis throughput and an S/N ratio in an analysis of a minor sample component mixed in various accompanying components by using the mass spectrometric device using the quadrupole ion trap.
