ABSTRACT:
A charged particle reaction cell of the present invention has a serially-arranged plurality of ring electrodes, wherein a modulated radio frequency voltage obtained by modulating the amplitude of a radio frequency voltage is applied, whereby ions are captured at the bottom of the ups and downs of a formed pseudopotential and are transferred with the move of the pseudopotential. In the charged particle reaction cell, the time required for the charged particle reaction can be secured and also the problem of the decrease of the throughput or the mass resolution can be solved, and the speed of the structure analysis of a measurement sample can be accelerated.
