Ammonium Ion Selective Electrode (ISE)

Use ammonium ion selective electrode (ISE) to measure the NH4+ ion in aqueous solutions.

Ammonium ISE is a half-cell probe, and is able to detect ammonium ions. This type of ISE is all-solid state, based on the carbon nanotube technology. As  result, this sensor is built-up with robust body, solid-state and membrane selective area. Ammonium ion selective electrode is compatible for use with any Ion or mV meter and a reference electrode.

Above all, the ammonium sensor is ideal for measuring NH4+ concentrations in drinking water, tap water, wastewater and general water quality applications:

  • Unique solid-state sensor nanotechnology inside.
  • Requires virtually zero maintenance.
  • Provides fast, stable, and accurate response in a variety of sample types.
  • Replaceable sensor tip.

Where is ammonium measurement required so far?

Ammonium ion is mainly encountered as a waste product in municipal wastewater in the form of urea. As a consequence, water sources with an ammonium concentration of 1 mg/l are not suitable. The use the ammonium ion selective electrode  helps to know your water quality and avoid serious problems.

Some specific use of the ammonium electrode are; for example:

  • Studying the spread of harmful substances from diffuse sources.
  • Monitoring aquaculture crops to point out dirtiness due to excessive nutrient concentration.
  • Monitoring nutrient content in natural waters.
  • Measure ammonia introduced from fertilizers.
  • Can monitore the equilibrium and indicate aqueous ammonia levels when samples are acidified to convert NH3 to NH4+.
