Online nitrite measurement can be carried out via either an UV absorbance method or a colorimetric method.
Nitrite has an absorbance peak at low UV wavelengths and due to the low maintenance of operating a UV sensor and the wide dynamic it offers, is often the preferred method.
In some applications, it may be preferable to combine chromatography with UV analysis in order to ensure separation of nitrate and nitrite prior to UV analysis.
For low levels of nitrite, a colorimetric method is often used.

RAS are finely balanced ecosystems, requiring careful control of the water quality to maximise yields and avoid a catastrophic loss of stock. Utilising simple pH and dissolved oxygen(DO) control sometimes isn’t sufficient.
Nitrate and nitrite are notoriously hard to quantify when in solution together. In Anammox wastewater treatment processes, however, being able to separately monitor nitrite from nitrate is crucial.
