| abstract | (57) [Summary] [Object] An object of the present invention is to provide a method and apparatus for mass spectrometry in which the manufacturing cost of an interface is reduced. [Structure] Ions generated under atmospheric pressure are the first, second, third After passing through the vacuum chambers 4 and 6 separated by the pores 3, 5 and 7, they are guided to the MS section 8 for mass analysis. The first vacuum chamber 4 is adjacent to the atmospheric pressure portion, there is no vacuum pump for independently evacuating this chamber, and the bypass hole 26 provided in the wall having the second fine hole 5 is provided. After that, the gas is exhausted together with the second vacuum chamber 6 by a common pump. The pressure in the first vacuum chamber 4 can be set to several 100 Pa, and the pressure in the second vacuum chamber 6 can be set to several 10 Pa. In the first vacuum chamber 4, it is possible to achieve sufficient desolvation at an ion acceleration voltage of about 100 V and then suppress the spread of the velocity. Second In the vacuum chamber 6, the ions are accelerated at about 10 V and the spread of velocity can be suppressed as low as possible. |
