Description générale

Method: colorimetric with color-disk comparator 0.2 - 0.5 - 0.8 - 1.3 - 2.0 - 3.0 - 4.5 - 6.0 - 8.0 mg/l NH MQuant®
The MQuant® Ammonium test (formally MColortest®) measures both ammonium ions and dissolved ammonia in e.g. groundwater and surface water, drinking water and aquarium water. A pH-dependent equilibrium exists between the two forms.

Method
In strongly alkaline solution ammonia reacts with a chlorinating agent to form monochloramine. This in turn reacts with thymol to form a blue indophenol derivative. Due to the intrinsic yellow coloration of the reagent blank, the measurement solution is yellow-green to green in color. The ammonium 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.

The test is suitable for ammonium determination in
  • Groundwater and surface water
  • Drinking water and mineral water
  • Aquarium water, waters from aquaculture
  • Boiler and boiler feed water, cooling water
  • Process water
  • Wastewater
  • Electroplating wastewater
  • Swimming-pool water
  • Nutrient solutions for fertilization
  • Food after appropriate sample pretreatment

This test is not suited for seawater.
