✦ Synopsis

A new tandem mass spectrometer has been developed for the study of molecular fragmentation reactions. The first stage of this tandem mass spectrometer is a double-focusing sector field instrument in the BE configuration. The second stage is a double-focusing combination of a Wien filter and a sector magnet that allows simultaneous detection of a wide range of masses owing to the approximately equal velocities of the fragment ions. By using a microchannel plate as a collision target, high fragmentation effi.ciency and high ion transmission were achieved.
