Abstract

PURPOSE:To measure the content of impurities, by subtracting light intensity of domain of luminous wavelength of contained impurities and that of the domain of wavelength based on the main component of gas to be inspected from a combustion light of the gas to be inspected mixing impurities. CONSTITUTION:A fuel gas (g) essentially consisting of hydrocarbon gas as a gas to be inspected, is burnt by a burner 1 together with gaseous hydrogen mixed with air. A light of domain of 390nm wavelength (a) and that of 500nm wavelength (b), are obtained alternately by a rotating filter 3 provided with a transmitting window transmitting a combustion light of sulfur of doman of 390nm wavelength from a combustion light 2 and that of transmitting the light 2 of the fuel gas of domain of 500nm wavelength. Light intensity of the domain of 500nm wavelength is close to that of the combustion light of desulfurized fuel gas in the domain of 390nm wavelength. The lights (a), (b) are converted into electric signals by a photoelectric converter 4 and said signals are amplified to a prescribed level by an amplifier 5 and then, a content of sulfur containing in the fuel as an impurity, is detected by said signal treatment.
