Spectrophotometric analyzer for the determination of the nitrate ion in water. The UVNO3 analyzer rely on the measuring principle of UV light absorption of the chromophores NO₃^–/NO₂^–. The measurement is the weighted sum of the nitrate and nitrite concentration. As the concentration of NO₃^– or NO₂^– increases, UV absorption also increases. In many most applications the NO₂^– concentration is negligible and this is reason why it’s usually considered NO₃^– measurement. Results are reported on the touchscreen display in mg/L or ppm of NO₃ , NO₂₊₃ , NO₃-N or NO₂₊₃-N. The measuring, calibration and cleaning frequency can be programmed by the user.
Nitrates are dangerous pollutants for aquatic life and poses risks to human health when present in drinking water. The nitrates concentration in surface waters derive mainly from biological pollution due to urban agglomerations, agriculture nitrogenous fertilizers, discharges from chemical industries and combustion processes. The instrument is ideal for potable water or surface water analysis and with the addition of a dilution module is also capable of the determination of nitrates in complex matrices such as urban and industrial wastewaters.
