This system is designed to monitor carbon dioxide (CO₂) emission concentrations from stationary sources. It is primarily used at fixed discharge outlets of major energy-consuming industries such as power generation, petrochemicals, steel, and waste incineration (including landfill and hazardous waste treatment).
Based on the direct extraction condensation method, the system utilizes gas filter correlation (GFC) technology, combined with a custom-designed long-path gas absorption cell (L-Cell), wavelength filter, infrared detector, and a high-precision signal processing circuit to perform quantitative analysis of gases in the infrared band.
