Abstract
The present invention provides a mass spectrometer capable of breaking even a sample molecule having a large molecular weight by a CID process. In an embodiment of the present invention, the mass spectrometer includes an ionizing sourcefor turning a sample into ions, mass-separating sectionsandfor mass-separating the sample ions, a detecting sectionfor detecting the mass-separated ions, and a collision section (collision cell)located on an ion path extending from the ionizing sourcethrough the mass-separating sectionsandto the detecting section. It also includes a cluster generatorfor producing clusters of atoms or molecules. The clusters produced by the cluster generatorare introduced into the collision cell. The use of the clusters having a huge mass as the target gas in the CID process enables the collision energy of the sample ions to be efficiently assigned to the breaking of the ions.
