Product description:Special reagent for monitoring of nitrogen dioxide in the atmosphere. Nitrogen dioxide in the air is absorbed by the liquid nitrogen dioxide absorption and diazotization reaction generated pink azo dye. Generated azo dye the strongest and ultraviolet-visible absorption wavelength of 540 nm absorbance proportional to the content of absorbed nitrogen dioxide.
