Device for collaborative detection of carbon and nitrogen emissions and method thereof

Abstract

A device for collaborative detection of carbon and nitrogen emissions and a method thereof are provided. The device includes an integrating cavity, a single beam laser and a dual beam hybrid laser set at opposite ends of the integrating cavity, and an information acquisition and analysis system. The single beam laser and the dual beam hybrid laser are respectively used to continuously emit and transmit laser beams into the integrating cavity. The single beam laser and the dual beam hybrid laser can achieve simultaneous spatio-temporal high-frequency detection of any concentration of CO—CH—NO—Nmixed gas in one integrating cavity, and the concentration of CO, CH, and NO can be inverted through the information acquisition and analysis system. This device meets the research demand for simultaneous detection of multiple greenhouse gases under the same path, greatly improving the utilization efficiency of the integrating cavity and saving detection costs.
