Optical gas concentration measuring method |
| abstract |
[Problem] A concentration measurement method capable of accurately and quickly measuring the concentration of a predetermined chemical component non-destructively up to the concentration of a trace region by a simple means, and the concentration of a chemical component in a measurement target accurately and quickly To provide a concentration measurement method having versatility that can measure in real-time even the ultra-trace concentration range of the nano order, and can be realized in various shapes and forms. [Solution means] Light of a first wavelength and a light of a second wavelength having different light absorption rates with respect to the measurement object are irradiated to the measurement object by a time-sharing method, respectively, and the measurement object is irradiated with the light of each wavelength. receives light of each wavelength optically through a common light receiving sensor, and forms a differential signal between the signal related to the light of the first wavelength and the signal related to the light of the second wavelength output from the light receiving sensor according to the received light Then, the concentration of the chemical component in the measurement target is derived based on the differential signal. |
