Ambient air. Determination of mass concentration of nitrogen dioxide. Modified Griess-Saltzman method1 Scope This International Standard specifies a modified Griess Saltzman method for the determination of the mass concentration of nitrogen dioxide present in ambient air. The method is applicable to the determination of the mass concentration of nitrogen dioxide present in ambient and confined air within the range 0,003 mg m3 to 2 mg m3 and for sampling times between 10 min and 2 h. Substances present in the air mass under investigation, and thus in
