NO3-N - What is Nitrate?

Nitrate measurement is an important water quality parameter used to indicate water pollution. Nitrate may be determined using on-line instrumentation or by using portable/laboratory water analysis. Water intake protection monitoring may include nitrate measurement using on-line instrumentation in catchments exposed to significant agricultural surface water runoff. Nitrate measurement may also be performed after nitrification to measure treated water quality.

Various technologies are available accommodating different application requirements. The Trios sensor technology use the latest UV spectral analysis to report nitrate, nitrite or NOx with optional compressed air cleaning. The same sensor technology can be integrated into the Chemitec 50 series controller. Nitrate ISE (Ion Selective Measurement) technology is available from WTW, with the possibility of automatic compressed air cleaning. The 3S analytical platform uses UV absorption combined with chemical cleaning and automatic zero adjustment which may be used where very hard water or precipitates causes scaling.
