Chemical Oxygen Demand (COD) Test KitsChemical Oxygen Demand (COD) Test Kits
(W1704) 		CHEMetrics offers two dichromate reactor digestion methods for fast, easy, safe determinations of low-, mid-, and high-range COD levels in wastewater: the USEPA-approved method, and a mercury-free method. The products using the USEPA-approved method contain mercuric sulfate in the reagent to eliminate chloride interferen... $144.05
Alkalinity Test KitsAlkalinity Test Kits
(W2000) 		CHEMetrics' total alkalinity tests determine total or M alkalinity using a hydrochloric acid titrant and a bromocresol green/methyl red indicator. The end point of the titration occurs at pH 4.5. Results are expressed as ppm (mg/L) CaCO3. For hydrate alkalinity, CHEMetrics developed a titrimetric method that uses a hydro... $27.16
Ammonia Test KitsAmmonia Test Kits
(W2020) 		The 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. In some waters, calcium and magnesium concentrations can cause cloudiness of the reagent. Adding a few drops of ... $45.94
Bromine Test KitsBromine Test Kits
(W2045) 		Bromine, a less volatile compound than chlorine, is used as a sanitizing agent in drinking water systems, swimming pools, and spas. The DDPD Reagent, a methyl-substituted form of DPD is employed. Potassium iodide is added to the sample before analysis. Bromine reacts with the iodide to liberate iodine. The iodine reacts ... $53.78
Carbon Dioxide (Dissolved) Test KitsCarbon Dioxide (Dissolved) Test Kits
(W2060) 		Dissolved carbon dioxide (CO2) is naturally present as a result of animal respiration, the decay of organic matter, and the decomposition of certain minerals. It is the major source of acidity in unpolluted water samples. Surface waters typically contain less than 10 ppm (mg/L) dissolved CO2, while ground waters, particu... $27.16
Chloride Test KitsChloride Test Kits
(W2080) 		Chloride is the most common inorganic anion found in water and wastewater. A limit of 250 mg/L Cl has been placed on drinking water supplies, as this is the level at which water begins to taste salty when sodium is the cation. Natural sources of salt are the ocean and various salt deposits above and below ground. Chlorid... $27.16
Chlorine Test KitsChlorine Test Kits
(W2120) 		Because of its strong oxidizing properties, chlorine is an excellent biocide used to treat potable waters, municipal wastes, and swimming pools. When used to treat potable water, chlorine helps alleviate the adverse effects of iron, manganese, ammonia, and sulfide. The DPD Method: In the USEPA-approved DPD meth... $112.73
Chlorine Dioxide Test KitsChlorine Dioxide Test Kits
(W2125) 		Chlorine dioxide is used as an oxidizing microbiocide in industrial cooling water treatment, the dairy industry, the meat industry, and many other food and beverage industry applications. It is used as a bleaching agent in the pulp and paper industry, and as a disinfectant in municipal water treatment. Industrial waste t... $53.78
Chromate (hexavalent) Test KitsChromate (hexavalent) Test Kits
(W2130) 		Hexavalent chromium salts are used in numerous industrial processes. They are also used extensively as corrosion inhibitors in open and closed cooling water systems. With the chromate test method, hexavalent chromium reacts with diphenylcarbazide under acid conditions to form a red-violet color. Results are quantified ph... $53.78
Copper (soluble) Test KitsCopper (soluble) Test Kits
(W2140) 		Copper is naturally present in the earth's crust and in seawater. Copper-containing fungicides are used to control biological growth in water supplies. A 0.3 mg/L copper limit for potable water has been established. Concentrations above 1 mg/L will impart a foul taste to water and can be toxic to fish. The measurement of... $53.78
Detergents (anionic surfactants, MBAS) Test KitsDetergents (anionic surfactants, MBAS) Test Kits
(W2155) 		Detergents can be introduced into the water supply by industry, soap manufacturers, and private households. Environmental analysts often include a determination of anionic detergents when assessing surface water pollution. The methylene blue active substances (MBAS) method is used in a 3-minute procedure to measure anion... $71.91
Formaldehyde Test KitsFormaldehyde Test Kits
(W2182) 		Formaldehyde, a toxic substance, is used in the following applications: metal plating baths, textile treatments, biological specimen preservatives, and disinfectants of medical equipment. Commercial formaldehyde gas is readily soluble in water. The Purpald Method: Purpald® is subject to fewer interferences than Shiff... $53.78
