A concise introduction is presented to the theory and application of quadrupole ion trap mass spectrometry. The presentation of the theoretical treatment is based on a demonstration of the equivalence of the force acting on an ion in a quadrupole Γeld and the force derived from the Mathieu equation
The fullerenes C,, and C,, can be ionized by desorption from a liquid matrix upon bombardment by Cs' ions of 7 keV kinetic energy. The resulting radical cations, when activated in the ion trap by collisions with Xe target, in the presence of helium, undergo extensive dissociation by loss of multiple
This paper is a presentation of recent key developments in quadrupole ion trap mass spectrometry. These key developments have been made in three areas; namely, the trapping of ions generated externally to the ion trap, the fine control of the trajectories of ions confined within the ion trap, and th
