What is Ammonia?
Ammonia is an inorganic form of nitrogen that contains hydrogen. It is a plant nutrient often found naturally in water at low levels due to the decomposition of organic matter. When ammonia levels range too high, it usually signals contamination stemming from raw sewage, industrial effluents (particularly petroleum refineries), or fertilizer runoff. Total ammonia is the sum of both NH3 (ammonia, the un-ionized form) and NH4+ (ammonium, the ionized form). Total ammonia is what is measured analytically in water. Ammonia toxicity is influenced by pH and temperature. As pH or temperature increases, NH4+ is converted to NH3, and the toxicity also increases.
Why Test for Ammonia?
Ammonia is toxic to aquatic life, and the aquaculture industry frequently measures and controls its concentration to keep fish and shellfish alive. Regulatory requirements mandate ammonia testing and monitoring for diverse industries to protect downstream aquatic environments. Examples include wastewater, landfill, acid mine drainage and animal feeding operations where ammonia is measured in effluent, leachate, and unintended discharges. Environmental groups often test for ammonia in water bodies as part of their monitoring program to help them assess trends associated with other aquatic health indicators.
About our Test Kits
CHEMetrics offers ammonia testing kits using two different methods: Direct Nesslerization and Hydroxybenzyl Alcohol (HBA). Visual and instrumental ammonia testing kit formats that span low and high measurement ranges are offered. Test results for visual test kits use color comparators for analysis while instrumental kits rely on CHEMetrics direct-readout photometers or spectrophotometers capable of accepting a 13-mm diameter round cell
