Nitrite

Online nitrite measurement can be carried out via either an UV absorbance method or a colorimetric method.

Due to an absorbance peak at low UV wavelengths, a low maintenance of operating a UV sensor and the wide dynamic it offers, UV 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.
