ActiveGas analysis—Determination of sulfur dioxide and nitrogen oxides—Ultraviolet differential optical absorption spectroscopy
气体分析 二氧化硫和氮氧化物的测定 紫外差分吸收光谱分析法
Application Summary AI generated
This standard specifies the use of ultraviolet differential optical absorption spectroscopy (UV-DOAS) for measuring sulfur dioxide (SO₂) and nitrogen oxides (NOx) in gas samples. It is primarily applied in environmental monitoring and industrial emission testing, such as analyzing flue gas from power plants, steel mills, or chemical facilities to ensure compliance with air pollution regulations. The method provides a non-contact, real-time analysis technique suitable for continuous emission monitoring systems (CEMS) in stationary source applications.
