一般說明
Method: reflectometric with test strips 0.03 - 1.00 g/l NO₂⁻ Reflectoquant®
Nitrite is naturally present in soil, water and food, and regularly testing its concentration is essential for many applications. Nitrites 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 keeping properties 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, nitrite ions react with an aromatic amine to form an orange-red azo 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.
