Abstract
An ionization chamber side voltage contact point is formed so as to protrude from the compartment in the ionization chamber, a mass spectrometric unit side voltage contact pointis formed in the hole created in the housing of the mass spectrometric unit, and a predetermined distance is provided between the inner periphery of the hole and the outer periphery of the mass spectrometric unit side voltage contact point in the structure, which allows the ionization chamber side voltage contact point to be inserted into the hole so to be connected to the mass spectrometric unit side voltage contact point when the ionization chamber is in the analysis position and allows the ionization chamber side voltage contact point to be pulled out from the hole so as to be disconnected from the mass spectrometric unit side voltage contact point the ionization chamber is in the maintenance position.
