General description
\nWith the MQuant\u00ae Ammonium test (formally MColortest\u00ae) ammonium ions can be detected in e.g. groundwater and surface water, seawater, drinking water and aquarium water. Ammonium nitrogen (NH4-N) occurs partly in the form of ammonium ions and partly as ammonia. A pH-dependent equilibrium exists between the two forms.<\/p>\n
Method
\nIn 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 semi-quantitatively by visual comparison of the color of the measurement solution with the color fields of a color card.The unique brilliance of the print and their fine color graduation allow precise analyses, even at the lower end of the concentration range. Due to the long test tubes a sensitive measurement range can be covered.<\/p>\n
This test is suitable for ammonium determination in
\nGroundwater and surface water
\nDrinking water and mineral water
\nWastewater
\nAquarium water, waters from aquaculture
\nBoiler and boiler feed water, cooling water
\nSwimming-pool water
\nNutrient solutions for fertilization
\nFood after appropriate sample pretreatment<\/p>\n
This test is not suited for seawater.
