Abstract

PURPOSE:To completely prevent the memory phenomenon by providing a primary beam shielding body near the periphery where an opening specifying the seeping region of a sample liquid is in contact with the surface of a porous member. CONSTITUTION:A porous member 10 is fitted to the tip of a tube 7 guiding a sample liquid into an ion source 2 from the outside, the seeping region of the sample liquid seeping on the surface is specified by an opened cap 13, and an orifice plate 15 with a window smaller than an opening 12 is fitted at the tip of the cap 13. Even if the sample liquid is accumulated at the peripheral portion (a) of the opening 12 of the cap 13, this portion is shielded by the orifice plate 15 according to this constitution, no primary beam is radiated and ionized. The ion source of a mass spectrograph completely preventing the memory phenomenon can be obtained.
