Scope

Scope: This document specifies the test method for determining ammonia nitrogen in water based on an enzyme analyzer. This document is applicable to the determination of ammonia nitrogen (calculated as N) in surface water, groundwater, domestic wastewater, industrial wastewater, and seawater. When the water sample volume is 200 μl and the colorimetry is performed using a 96-well microplate, the detection limit of this method is 0.012 mg/L, the minimum detection limit is 0.048 mg/L, and the linear range is 0.10 mg/L~2.0 mg/L (all calculated as N). Main technical content: 1. Basic provisions 2. Sampling and detection procedures 3. Data processing and data quality assurance
