Abstract
Elements are arranged so that a straight ion-beam axis extending from an ion source through a first ion lens and a front-stage quadrupole mass filter and a straight ion-beam axis extending through the ion guide in a collision cell and a rear-stage quadrupole mass filter obliquely intersect with each other at a predetermined angle in a space between the front-stage quadrupole mass filter and the collision cell. Metastable helium molecules generated in the ion source may pass through the front-stage quadrupole mass filter but will be removed before reaching the exit of the collision cell. On the other hand, precursor ions which have passed through the front-stage quadrupole mass filter are made to bend along an inflected ion-beam axis under the influence of a direct-current electric field created by an entrance ion lens, to be efficiently introduced into the collision cell.
