Параметър: Total Nitrogen (TN), Nitrate, Nitrite
Проба, дебит: 100 - 300 mL/min
Проба, качество: Maximum particle size 100 µm, < 0.1 g/L; Turbidity < 50 NTU
Проба: налягане: By external overflow vessel

Смущения: Antimony (III), Bismuth (III), Chloroplatinate, Gold (III), Iron (III), Lead (II), Mercury (II), Metavanadate, and Silver (I) can precipitate with Nitrate. The presence of Copper (II) may decompose the diazonium salt which results in a low result. Strong oxidising agents. NCl₃ results in a false red colour. Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
