Claim 8:
9. A mass spectrometry device comprising a vacuum container in which an ionizer that ionizes a sample separated in a separator and produces ions, a mass separator that performs mass separation on the ions produced in the ionizer and a detector that detects ions obtained by mass separation in the mass separator are arranged, and
the mass spectrometry device comprising:
an opening-closing portion provided at the vacuum container;
a cooling gas introducer that introduces a cooling gas for cooling the ionizer into the vacuum container;
a determiner that determines whether cooling of the ionizer is finished after the cooling gas is introduced into the vacuum container; and
a switcher that switches the opening-closing portion from a locked state of being locked in a close state to an unlocked state in a case where a result of determination made by the determiner represents that cooling is finished.
