DescriptionNitrite Test
OverviewNitrites must be closely monitored in drinking and groundwater as well as in process, waste, or aquarium water. In farm produce and fruit juices, high nitrate concentrations affect quality and can constitute serious health risks. Nitrites are also used in additives for food products and serve as corrosion inhibitors in engine cooling systems. On the Reflectoquant® Nitrite test strips, in the presence of an acidic buffer nitrite ions react with an aromatic amine to form a diazonium salt, which in turn reacts to form a red-violet dye that is determined reflectometrically on the RQflex®. For pre-testing a sample in an economic and quick way to estimate the nitrite concentration and a possible dilution factor prior to using this quantitative method we recommend our semi-quantitative MQuant® test strips for nitrite. Further quantitative determination methods can be found with our Spectroquant® tests.
