| Zusammenfassung: | A gas analyzing apparatus comprises: a tube-like member (11) that includes a light path through which measurement light is emitted to a predetermined measurement region of sample gas (S) flowing in a pipe (50) and/or through which the measurement light from the measurement region is received, the tube-like member being attached so as to penetrate a pipe side wall (51); an optical system member (12) configured to emit the measurement light to the sample gas (S) in the measurement region and/or to receive the measurement light from the measurement region; a purge gas feed portion (22, 23) configured to supply purge gas to a region positioned on a light path of the measurement light between the optical system member and the measurement region; and at least one blocking plate (21) disposed at a position so as to suppress the sample gas (S) from flowing into a gap (56) between the tube-like member (11) and the pipe side wall (51). |
