Abstract

PURPOSE: To prevent the dispersion of the ion detection sensitivity by allowing all ions transmitting a mass spectrometer to invariably collide with an ion/ electron converter at a constant incidence angle and with constant incidence energy without being affected by the value of the ion extracting voltage.
CONSTITUTION: A sub-slit 10 is arranged between a collector slit 2c and an ion/electron converter 4, and a voltage control means 12 determining Vs, Vc respectively in response to the setting of Vo is provided to satisfy the relations Vs=Vo- k1, Vc=Vo-k2, where Vo is the ion extracting voltage applied to an ion source 1, Vs is the voltage applied to the sub-slit 10, Vc is the converter voltage applied to the ion/electron converter 4, and k1, k2 are constants.
