API AMMONIA 130-Test Freshwater and Saltwater Aquarium Water Test Kit

Product Information

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.

CHEMets and VACUettes: 5 month limit on supply is recommended, however refrigeration can extend shelf-life.In the ammonia test method that employs the Hydroxybenzyl Alcohol chemistry, free ammonia reacts with hypochlorite to form monochloramine. Monochloramine reacts with HBA, in the presence of sodium nitroferricyanide, to form a green coloured complex. This test method measures the sum of free ammonia and monochloramine. Results are expressed in ppm (mg/l) ammonia-nitrogen, NH 3-N.

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 plant or animal matter. Higher concentrations in surface waters are toxic to aquatic life.

Simply run the water, open the test tube gently (do not twist the cap), and allow the water to dilute and rinse the contents out of the test tube. Avoid getting the contents of the test tube on your skin.

If the original sample contained ammonium ions, the basic reagents would convert it to molecular ammonia and then it will react and contribute to the final test result. However, these simple ammonia tests do not include the ammonia that is in organically bonded amino groups. A true total ammonia test would include chloramines and require heating the sample in an acidic solution to digest the organic ammonia.
