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

Product Information

The chemical equation that drives the relationship between ammonia and ammonium is: NH3 + H2O ↔ NH4+ + OH- This is our most popular ammonia assay kit; ammonia assay kit ab102509 uses an alternative non-enzymatic method. When the pH is low, the reaction is driven to the right, and when the pH is high, the reaction is driven to the left. In general, at around room temperature, at a pH less than 6.0, the proportion of ammonium-N plus ammonia-N as NH3 is very low and as NH4+ is very high. At a pH around 8.0 (the ammonia assay buffer pH), the proportion as NH3 is 10 percent or less. Saltwater tanks are typically fussier about their water quality levels, and the Salifert Master Reef Testing Combo Kit contains all the elements you need to keep an eye on things. A bit more expensive than other test kits on the market, this combo includes 50 to 100 calcium tests, 100 to 200 carbonate alkalinity tests, 60 phosphate tests, 50 magnesium tests, 60 nitrate tests, and 50 pH tests. Calcium, magnesium, phosphate, and carbonate alkalinity tests are especially important for monitoring corals. The tools you’ll find in each kit vary between syringes, spoons, testing vials, plastic tips, and a chart to find your reading.

Analytics and Sample Preparation > Test Kits and Photometric Methods > Areas of Application > Electroplating > Ammonium Q: My pH reagent has changed colour, is it still ok to use? A: Our pH reagent can change colour over time. It will start green, but can change to any colour on the colour chart. This is normal and you will still get accurate results. Ensuring good water chemistry in your aquarium is essential to fish health and wellbeing, and having a reliable and accurate test kit makes a difference. For a master test kit, we recommend the API Freshwater Master Test Kit for freshwater tanks and the Salifert Master Reef Testing Combo Kit for saltwater tanks. Both kits contain multiple tests to measure everything from pH to nitrate to nitrite and more to keep your water clean and healthy for your aquatic environment.

Q: My Ammonia 2 reagent has turned blue, is it still okay to use? A: Our Ammonia 2 reagent can take on a blue colour with time, but it does not affect the performance or results of the test. As long as the test kit is still within date, you can be confident in the reliability of the results it produces. Large pallet items like aquariums are deemed delivered successfully with no damage once the the driver has left the property. If a report of damage is submitted after the driver has left we may be unable to assist with replacements. We recommend refusing a damaged delivery, this is the fastest resolution.Ammonia in groundwater is normal, due to microbiological processes. However, the presence of ammonia nitrogen in surface water usually indicates domestic pollution. Excess ammonia can damage vegetation and is incredibly toxic to aquatic life, especially at elevated pH and temperature levels.

At physiological pH, nearly all ammonia will exist as ammonium in solution.A new, dedicated SAM Photometer A-2024 is now available to measure both K-1413 and K-1513 test kits in both test ranges, giving a total of 4 possible test ranges. The Direct Nesslerisation Method Based on CHEMetrics patented Self-Filling Reagent Ampoule technology. Premixed. Premeasured. Precise. Each kit contains 30 tests. Visual and instrumental ammonia testing kit formats span low and high measurement ranges. CHEMets® and VACUettes® visual test kits use colour comparators for analysis while Vacu-vials® instrumental kits rely on CHEMetrics direct-readout photometers or spectrophotometers capable of accepting a 13-mm diameter round cell. This Spectroquant® Ammonium Reagent Test allows the cyanide-free quantification of ammonium in wastewater, groundwater, surface water, and seawater. Typically, ammonium enters water sources as runoff from fertilized agricultural areas and enhanced levels are important indicators for fecal pollution.

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. Ammonia is a colorless, pungent gaseous compound of hydrogen and nitrogen (one nitrogen atom and three hydrogen atoms, NH 3) that is highly soluble in water. Oxidation of 5-aminosalicylate is carried out in the presence of a catalyst, nitroprusside (also called nitroferricyanide), which results in the formation of indosalicylate, a blue-colored compound. The blue color is masked by the yellow color (from excess nitroprusside) causing a green-colored solution. The intensity of the resulting green color is directly proportional to the ammonia concentration in the sample.

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 Analytics and Sample Preparation > Test Kits and Photometric Methods > Base Parameters from A to Z > Ammonium The Hanna Instruments-3824 ammonia test kit determines the ammonia concentration in water in several easy steps. The Nessler reagent reacts with ammonia, under strong alkaline conditions, to form a yellow coloured complex.
