PURPOSE:To eliminate hindrance of an interfering component by the difference in luminescence positions and to enable measurement of multicomponents, by considering the properties that luminescence times differ dependent on kinds of reactants, and using a long reaction tube along the path of gases. CONSTITUTION:The reaction tube 11 of a chemical luminescence analyzer has a sample gas inlet 12 and a reagent gas inlet 13 on one end of the tube 11, and a gas outlet 14 on the other end. The tube 11 has a long form along the flow paths of the gasses. Said 2 gases are passed trough the inlets 13, 14, respectively, and the gases are exhausted from the outlet 14. The 2 gases are reacted in the tube 11 and causes chemical luminescence, and it is detected with a light detector 15. When the luminescence time of the measurement object component A is later and that of the interference component B is earlier, concn. of the component A can be measured by detecting the luminescence at a position (a) with the detector 15 without being affected by the interference component B. |
