How to Detect Ultra-low Emission of Exhaust Gas with Micro Spectrometer

The problem of air pollution has gradually become the focus of wide attention from all walks of life. As a major polluter, the emissions of coal-fired power plants or boilers must strictly follow the emission standards. Therefore, Optosky provides the complete system project for environment.

We conduct actual tests on nitric oxide and sulfur dioxide, collect absorbance data, and the reference spectrum is the measurement spectrum without the gas to be measured.

The following figure shows an example map of the detection of a mixed gas of nitric oxide and sulfur dioxide:
  • Test conditions: normal temperature and pressure
  • Test equipment: Optosky micro-UV-VIS spectrometer ATP2002, pulsed xenon lamp.
  • The light path is a folding gas pool with a total light path of 5m.
  • The concentration of nitric oxide is 20.5ppm, and the concentration of sulfur dioxide is 5.1ppm.
In the above figure, the ordinate is the absorbance, and the abscissa is the wavelength. The characteristic absorption peaks in the red area are two characteristic absorption peaks of nitric oxide, where the partial absorption of sulfur dioxide is superimposed, and the two black areas are the characteristic absorption peaks of sulfur dioxide. On the basis of the absorbance signal, the user can use the differential algorithm to further separate and extract the original signal, or directly calculate the concentration of the gas to be measured based on the absorbance peak or area data, combined with the system calibration result.
