| Interferences | Ions, e.g., antimony (III) (Sb³⁺), bismuth (III) (Bi³⁺), chloroplatinate (PtCl₆²ˉ), gold (III) (Au³⁺), iron(III) (Fe³⁺), lead (II) (Pb²⁺), mercury (II) (Hg²⁺), metavanadate (VO₃ˉ) and silver (I) (Ag⁺) can cause precipitation with nitrate. Copper (Cu²⁺) ions can decompose the diazonium salt cause a low result. NCl₃ can cause a red colour. Strong oxidizing agents interfere. Large quantities of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar interfere. |

The EZ1000sc Series Analysers use colorimetric analysis to measure Nitrate.
- EZ1029sc Nitrate
Nitrate: 0.2 - 10 mg/L NO₃-N
Options:
- Multiple stream analysis (1-8 streams) reducing cost per sampling point
- Analogue and/or digital outputs for communication
Nitrate and Nitrite can also be measured in combination with Total Nitrogen. For this option please check the EZ7700 Series.
Some applications may require the use of a sampling/filtration or a external dilution system for sample preconditioning. For this option please check the EZ Series Sample Preconditioning page.
