ANALYSIS DEVICE AND ANALYSIS METHOD

WIPO Patent Application WO/2022/270202

A1

The present invention appropriately performs explosion-proof measures for an analysis device while suppressing the consumption amount of a purge gas. This analysis device (100) comprises a filling part (3), an irradiation part (5), a propagation part (7), a housing (1), a purge gas introduction part (40), and an explosion-proof gas introduction part (20). The filling part (3) is filled with a sample gas (SG) containing a gas to be measured. The irradiation part (5) emits measurement light (L) used to analyze the gas to be measured. The propagation part (7) is provided between the filling part (3) and the irradiation part (5), and forms a propagation space (TS) for causing the measurement light (L) emitted from the irradiation part (5) to propagate toward the filling part (3). The housing (1) stores the filling part (3), the irradiation part (5), and the propagation part (7). The purge gas introduction part (40) introduces a purge gas (PG) into the propagation space (TS). The explosion-proof gas introduction part (20) introduces an explosion-proof gas (EP) into the internal space of the housing (1).
