Original Abstract Submitted

In an ion analyzer which dissociates an ion using a radical generated from a source gas, a gas supplier () supplies the source gas by selecting a gas from multiple kinds of gases and/or mixing two or more of those gases. The source gas is introduced into a generation chamber (). A power supplier () supplies electric power for generating electric discharge within the generation chamber. A controller () controls those two suppliers as follows: When the radical is to be generated from a first gas through which electric discharge is relatively difficult to occur, the electric discharge is initiated by supplying electric power into the generation chamber while a second gas through which electric discharge occurs more easily is selected or mixed with the first gas and supplied to the generation chamber. After the electric discharge is initiated, the first gas is selectively supplied to the generation chamber.
