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.
一种新型串联质谱仪已经被开发出来用于研究分子碎裂反应。该串联质谱仪的第一级是 BE 构型的双聚焦扇形场仪器。第二级是由维恩滤波器和扇形磁铁组成的双聚焦组合，由于碎片离子的近似相等速度，允许同时检测大范围的质量。通过使用微通道板作为碰撞靶，可以实现高效率的碎裂和高离子传输。
