| titleOfInvention | A dual-channel measurement method and device for gaseous pollutants |
| abstract | The invention discloses a dual-channel measurement method for gaseous pollutants, comprising the following steps S1: capturing the polluted gas in the gas to be detected input from the outside, converting the polluted gas from a gaseous state to a liquid state, and obtaining a trapping liquid; S2 : carry out dyeing reaction on the capture liquid to obtain a dyeing reaction liquid; S3: pass monochromatic light of the corresponding wavelength into the dyeing reaction liquid, receive the light signal intensity of the monochromatic light transmitted by the dyeing reaction liquid and convert it into a measurement voltage Signal; S4: Calculate the pollutant concentration c according to Lambert-Beer's law, the preset zero-point voltage signal and the measured voltage signal. The invention is widely applicable to gaseous pollutants that can be measured by spectrophotometry; ultra-wide range measurement is realized by applying dual-channel detection, which meets the range requirements of wide variation range and large fluctuation of pollution source emission concentration; accuracy and portability are guaranteed; no manual labor is required. Calculation steps; fast measurement, high accuracy and low cost. |
