Abstract: A gas analyzing apparatus includes: an ionization device that generates an ion flow of a sample gas; an analyzer that analyzes the ion flow supplied from the ionization device; a first ion path that non-linearly guides the ion flow from the ionization device to an inlet of the analyzer; and a blocking device for intermittently blocking and releasing, using an electric field or a magnetic field, the ion flow on at least part of a path of the ion flow through the first ion path to a mass filter of the analyzer. It is possible to perform measurement in a state where the ion flow is blocked and measurement in a state where the ion flow is not blocked.

Abstract: There is provided a gas analyzer apparatus including: a sample chamber which is equipped with a dielectric wall structure and into which only sample gas to be measured is introduced; a plasma generation mechanism that generates plasma inside the sample chamber, which has been depressurized, using an electric field and/or a magnetic field applied through the dielectric wall structure; and an analyzer unit that analyzes the sample gas via the generated plasma. By doing so, it is possible to provide a gas analyzer apparatus capable of accurately analyzing sample gases, even those including corrosive gas, over a long period of time.
