ABSTRACT:
In a chemiluminescent analyzer for measuring a concentration of an object gas in a sample gas by mixing the sample gas with 5 a reaction gas and measuring light generated in a chemical reaction between the object gas and the reaction gas, the two gases flow through a double tube composed of an outer tube and an inner tube, and are mixed at the end of the tubes. The end of the inner tube is closed, and one or more outlets are provided at the side wall of the inner tube near the closed end. The flow of the gas coming out of the inner tube through the outlet or outlets crosses the flow of the gas in the outer tube, which enhances the mixture of the two gases and increases the chance of reaction between the object gas and the reaction gas. Since the flow of the mixed gas is directed toward the inner wall of the outer tube, the solid or liquid reaction product between the impurities in the sample gas and the reaction gas precipitates on the inner wall of the outer tube, not on a transparent glass plate separating the gases and the photometer for measuring the reaction emission (light).
