摘要： An ionization apparatus and ionization method, wherein an ion trap type structural unit is used as the ion source and an ion emitter for emitting metal ions is provided inside or outside the ion source, metal ions are attached to ingredients of a sample gas to ionize the sample gas, a separation parameter is changed to separate ions relating to a target substance for analysis and the metal ions, the metal ions are trapped and accumulated inside the ion source, and the ions relating to a target substance are ejected to a mass spectrometry unit. Due to this configuration, in ion mass spectrometry, it is possible to accurately separate the ions desired to be analyzed and the ions desired to be trapped by a simple configuration and relatively low resolution and possible to improve the sensitivity of analysis.

In the method, further, a pressure of the attachment region is set so as to be included in a pressure range enabling free flight of the metal ions and the attached ions in the attachment region, an electrostatic field is formed for decelerating the metal ions in the attachment region, and only the measured gas is introduced to the attachment region. Thereby, quantitative analysis enabling accurate measurement of the concentration of the measured gas is realized.
