A mass analysis apparatus is capable of performing a plurality of measurements in parallel by mounting a plurality of ion sources onto one mass spectrometer and speedily switching the ion sources. In a mass analysis apparatus for performing mass analysis by introducing ions produced in an ion source into a mass spectrometer, the mass analysis apparatus comprises a plurality of ion sources; and a deflecting means for deflecting ions from at least one ion source among the plurality of ion sources so that the ions travel toward the mass spectrometer by producing an electric field.
A mass analysis apparatus comprising a plurality of ion sources for ionizing a sample to be analyzed;
A mass analysis apparatus comprising a first chamber containing an ion source producing ions of a sample to be analyzed;
