    The average sampling time was 210 min. The qualitative detection limit was 0.2 µg/mL or 10.0 µg (as NH 3) when using a 50-mL solution volume. This corresponds to 0.60 ppm NH 3 for a 24-L air volume. The quantitative detection limit was 0.50 µg/mL or 25 µg (as NH 3) when using a 50-mL solution volume.

  • Nitrogen Ammonia Nh3 Nitrite No2 And Nitrate No3 - Water Quality

    Feb 27, 2021 · In a laboratory analysis, total ammonia (NH3 + NH4+) is measured and the distribution between unionized ammonia (NH3) and ionized ammonia (NH4+) is calculated from knowledge of the water pH and temperature at the sampling site. Since the unionized form is far more toxic to aquatic life than the ionized form, field measurements of water pH and temperature at the sampling site are very important.
