摘要:
The ionization chamber of the mass spectrometer is movable between the maintenance position for performing maintenance of the mass spectrometer unit and the analysis position for performing sample analysis, using a shielding plate synchronized with the motion of the ionization chamber where the shielding plate closes part of the aperture of the predetermined region when the ionization chamber is in the analysis position, whereas the shielding plate opens part of the aperture of the predetermined region when the ionization chamber is in the maintenance position so that connection tubes may pass through the part of the aperture of the predetermined region.
