ISO 9001:2000 Certified Bioscience, Inc Environmental Products and Services The accu-TEST™ COD Reactor Block is an economical solution for digestion of chemical oxygen demand (COD) samples. Double Reactor Block 30 vial capacity Single Reactor Block 15 vial capacity

Details of Chemical Oxygen Demand Test: 2mL of a water or watse water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. The tube is capped with a polypropylene, PTFE lined cap and heated in a block digester at 150C for 2 hours. The orange Hexavalent chromium is reduced to a greenish trivalent chromium.

Chemical oxygen demand (COD) is an indirect measurement of the amount of organic matter in a sample. With this test, you can measure virtually all organic compounds that can be digested by a digestion reagent. COD contrasts with biochemical oxygen demand (BOD), which relies on the use of microorganisms to break down the organic material in the

ISO 9001:2008 Certified Accu-TESTTM Micro-COD System The EPA accepted accu-TEST Micro-COD System offers fast, low-cost determination of chemical oxygen demand (COD). Description The micro-COD test determines the quantity of oxygen required to oxidize reduced compounds, including organic matter, in a water sample. This test requires a

The vial is placed in the COD reactor at 150 ° C for two hours. The samples then cool and the samples are tested using a spectrophotometer. The chemical oxygen demand value will be read in mg/L for both total COD (tCOD) and soluble COD (sCOD). For samples with a concentration of 0 to 150 mg/L, use the low range COD vials.

Jun 01, 2016 · A chemical oxygen demand (COD) test is used to measure the amount of organic compounds in a water sample. It measures the capacity of water to consume oxygen during the decomposition of organic matter and the oxidation of inorganic chemicals such as Ammonia and nitrate. The most common method uses COD vials with overall results being achieved
