1 Application scope This standard specifies fixed potential by electrolysis method for determining nitrogen oxides in stationary source emission. It is applicable to the determination of nitrogen oxides in stationary source emission. The detection limit of nitric oxide is 3mg/m3 (calculated in NO2) and that of nitrogen dioxide is 3mg/m3 when the method of this standard is adopted. The lower limit of determination is 12mg/m3 for nitric oxide (calculated in NO2) and 12mg/m3 for nitrogen dioxide. 2 Normative references The following documents or provisions therein are quoted in this standard.

In order to achieve the data quality object, the too high C.S. shall not be adopted when low-concentration nitrogen oxides (NOx) are determined. C.S. shall be less than or equal to the full span of the instrument
