Claim Text:
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 comprising a sample gas introducing unit that introduces the sample gas and a standard gas, and receives a luminescence inducing gas, and further comprising a light detector 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 connected to the gas analyzing unit 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 coupled to the gas analyzing unit and the luminescence inducing component generating unit and programmed 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.
