摘要： 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).

摘要： Relation of the degree of interference to interference concentration is previously stored with respect to at least one interference gas influencing an oxygen indicated value of a sample gas, so that interference corresponding to interference gas concentration of the sample gas is corrected on the basis of the stored relation when oxygen concentration is calculated from a detection signal of an oxygen sensor and outputted. Concentration of the interference gas, with respect to which the relation of the degree of interference is stored, is manually inputted in measurement, or previously set. When the concentration of the interference gas is previously set, such concentration is made changeable by manual input. Thus, even if the sample gas contains an interference gas in high concentration as in the case of an exhaust gas containing highly concentrated CO.sub.2 gas, it is possible to accurately measure oxygen concentration of the sample gas.
摘要翻译：相对于影响样品气体的氧气指示值的至少一种干扰气体，预先存储干扰浓度的关系，从而基于所存储的样本气体来校正对应于样品气体的干扰气体浓度的干扰当从氧传感器的检测信号计算氧浓度并输出时，关系。干扰气体的集中，相对于存储干涉程度的关系，在测量或预先设定的情况下手动输入。当预先设定干扰气体的浓度时，可以通过手动输入来改变浓度。因此，即使在含有高浓度CO 2气体的废气的情况下，即使样品气体含有高浓度的干扰气体，也能够精确地测定样品气体的氧浓度。
