- Scope
- This standard specifies the flow chemical analysis method for inorganic nitrogen and active phosphate in seawater. This method is suitable for the determination of inorganic nitrogen and active phosphate in seawater in oceans, coastal waters and estuaries. The measurement range of ammonia nitrogen is 0.005 mg/LN～1.0 mg/LN; the measurement range of nitrate nitrogen and nitrite nitrogen is 0.005 mg/LN～1.0 mg/LN and 0.004 mg/LN～0.1 mg/LN respectively; active phosphoric acid The measurement range of salt is 0.0024 mg/LP～0.30 mg/LP.
