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.
