A gas analyzing apparatus includes a gas analyzing unit, a luminescence inducing component generating unit, and a measurement signal calculating unit. The gas analyzing unit receives a sample gas containing a component gas and/or a standard gas and the luminescence inducing gas. The gas analyzing unit is configured to output a detection signal based on an intensity of a reaction light generated by the interaction between the component gas and the luminescence inducing component. The luminescence inducing component generating unit generates the luminescence inducing gas by electric discharge generated repeatedly at specified intervals. The measurement signal calculating unit calculates a first measurement signal based on a first detection signal, based on the reaction light generated when the sample gas and the luminescence inducing gas are introduced, and a second detection signal, based on the reaction light generated when the standard gas and the luminescence inducing gas are introduced. |

1. A gas analyzing apparatus for measuring a concentration of a component gas in a sample gas using a chemical luminescence analysis method, the gas analyzing apparatus comprising:
a gas analyzing unit, into which the sample gas and/or a standard gas and a luminescence inducing gas are introduced, configured to output a detection signal based on an intensity of a reaction light, the reaction light being generated by interaction between the component gas and a luminescence inducing component in the luminescence inducing gas; a luminescence inducing component generating unit configured to generate the luminescence inducing gas by electric discharge and to introduce the generated luminescence inducing gas into the gas analyzing unit, the electric discharge being generated repeatedly at a discharge interval, the discharge interval being determined based on the concentration of the component gas; and a measurement signal calculating unit configured to calculate a first measurement signal for measuring the concentration of the component gas based on a first detection signal and a second detection signal, the first detection signal being outputted when the sample gas and the luminescence inducing gas are introduced into the gas analyzing unit, and the second detection signal being outputted when the standard gas and the luminescence inducing gas are introduced into the gas analyzing unit. |
