GB/T 37186-2018
Gas analysis—Determination of sulfur dioxide and nitrogen oxides—Ultraviolet differential optical absorption spectroscopy

GB/T 37186-2018 "Gas analysis - Determination of sulfur dioxide and nitrogen oxides - Ultraviolet differential optical absorption spectrometry" specifies the method for determining the concentrations of sulfur dioxide and nitrogen oxides (such as nitric oxide and nitrogen dioxide) in gases using ultraviolet differential optical absorption spectrometry. This standard is applicable to the automatic online measurement of the aforementioned components in ambient air, such as flue gas emissions from stationary pollution sources, and industrial process gases.
