- Scope
- This standard specifies the mercaptocotton enrichment-cold atomic fluorescence spectrophotometric method for the determination of mercury and its compounds in ambient air. This standard applies to the determination of mercury and its compounds in ambient air. The detection limit of this standard method is 0.1mg/10ml sample solution. When the sampling volume is 15L, the detection limit is 6.6×10mg/m and the lower limit of determination is 2.6×10mg/m
