摘要： The present invention provides a mass spectrometry capable of high-efficiency and high-throughput ECD. An electron source and a two-dimensional combined ion trap in which a magnetic field along and generally parallel to a central axis is applied are used, thereby to achieve the foregoing object. First, precursor ions are trapped. By adopting the two-dimensional combined ion trap, it is possible to obtain a high ion trapping efficiency upon being injected and trapping. Subsequently, electrons are made incident thereon in such a manner as to be wound along the central axis to which no radio frequency is applied by using a magnetic field. For this reason, it is possible to allow energy-controlled electrons to reach the precursor ions. It is possible to implement a mass spectrometer capable of avoiding heating due to a radio frequency electric field, and effecting high-throughput/high-efficiency ECD.
