General description

Method: colorimetric with color-disk comparator 0.1 - 0.2 - 0.4 - 0.6 - 1.0 - 1.8 - 3.0 - 6.0 - 10 mg/l NO MQuant®
Nitrite is naturally present in soil, water and food, and regularly testing its concentration is essential for many applications. With the MQuant® Nitrite test (formally MColortest®) Nitrites can be closely monitored in drinking and ground water as well as in process, waste, or aquarium water. The test can be used in:
  • Groundwater and surface water, seawater
  • Drinking water and mineral water
  • Waters from aquaculture
  • Boiler and boiler feed water, cooling water
  • Wastewater and electroplating wastewater
  • Food after appropriate sample pretreatment
  • Soils after appropriate sample pretreatment

Method
In acidic solution nitrite ions react with sulfanilic acid to form a diazonium salt, which in turn reacts with N-(1-naphthyl)ethylenediamine dihydrochloride to form a red-violet azo dye. The nitrite concentration is measured semiquantitatively by visual comparison of the color of the measurement solution with the color fields of a color disk. The test evaluates the color reaction based on the transmitted light method. So even turbid and colored water samples can be analyzed without further preparation.
The color disk is made of very durable, lightfast plastic, thus suitable for industrial areas and wet environments.
