摘要：
An apparatus for mass-analyzing ions that are generated by bombarding sample components supported by a target by a primary beam. The mass spectrum data thus obtained is preferably as correct as possible. To satisfy this requirement, mass number sweeping is started after the quantity of ions generated from the sample components becomes gets stabilized.
