Gaseous ammonia and its concentrated solutions must be handled with care and in accordance with OSHA (or other relevant regulatory agency’s) requirements. This is due to highly corrosive properties that pose serious health risks ranging from mild eye or skin irritation to chemical burning, depending on the concentration. Additionally, off-gassing ammonia can cause aesthetic problems like objectionable taste or odor.

The salicylate method is a variation of the well-known phenate method, but it has an advantage of being free from mercury salts and phenol. This method is most useful for low range ammonia nitrogen determinations. Although the procedure involves multiple steps before a final green color is developed, all reagents are contained in convenient powder pillows (salicylate reagent powder pillows and alkaline cyanurate powder pillows) or a combination of powder pillows and TNT vials.Is it correct for the #2 bottle in the API AMMONIA TEST KIT to have a slightly bigger hole in the spout than the #1 does? I’m concerned my test kit isn’t accurate because of this. When ammonia is not used for disinfection, its presence in a distribution system may indicate leaching from materials used in the pipework construction or water contamination, due to damage in the system. When unwanted ammonia combines with chlorine, it diminishes the disinfection strength of chlorination. Chloramination The test measures both ammonium ions and dissolved ammonia in e.g. groundwater and surface water, seawater, drinking water and aquarium water. The test kit contains the easy to use colour card.

Categories Analytics and Sample Preparation > Test Kits and Photometric Methods > Areas of Application > Drinking Water > Ammonium The CHEMetrics Ammonia test kits employing the well-established Nessler reagent* to determine ammonia concentrations are applicable to drinking water, clean surface water, good-quality nitrified wastewater effluent, and seawater testing. The supplied stabiliser solution is used with some waters where the calcium and magnesium concentrations causes cloudiness of the reagent. Adding a few drops of the stabiliser solution (Rochelle Salt) will prevent this cloudiness. References recommend distilling samples prior to analysis. Results are expressed as ppm (mg/l) ammonia-nitrogen, NH 3-N.We highly recommend testing your aquarium or pond water regularly, to ensure it remains a safe and healthy home for your fish. Testing of levels such as pH, ammonia, and nitrite can help you determine whether you may be overfeeding, and alert you to any potential issues early, when they are more easily treatable. If your water tests show that any of your water parameters are very high or very low, it is important to take steps to correct conditions for fish health and wellbeing. Monitoring the water chemistry of the aquarium or pond will allow you to catch problems before they develop. Krom, Michael D., Spectrophotometric Determination of Ammonia: A Study of a Modified Berthelot Reduction Using Salicylate and Dichloroisocyanurate, The Analyst, v.105, pp. 305-316, 1980. 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. Higher ammonia concentrations in surface waters can indicate contamination from waste treatment facilities, raw sewage, industrial effluents (particularly oil refineries), or fertiliser runoff. Regulatory requirements mandate ammonia monitoring for diverse industries to protect downstream aquatic environments, such as wastewater, landfill, acid mine drainage and animal feeding operations, where ammonia is measured in effluent, leachate, and unintended discharges. Environmental scientists often test water bodies for ammonia to help them assess trends associated with other aquatic health indicators. The aquaculture industry frequently measures and controls ammonia concentration to keep fish and shellfish alive and healthy. The Specified Concentration or Value (SCV) for ammonia in drinking water supplies in the UK is 0.50 mg/l (ppm), and in Ireland is 0.3 mg/l (ppm). What is Ammonia?
