Blank = 0 mg/L Standard = 385 mg/L Sample waste = 23 mg/L Discussion The Chemical Oxygen Demand (COD) test is used widely to estimate the amount of organic matter in wastewater. It is a measurement of the oxygen equivalent of the materials present in the wastewater that are subject to oxidation by a strong chemical oxidant, in this case, dichromate.
Combined with the InMotion Autosampler Flex Base and 100 mL Rack; the Chemical Oxygen Demand Kit is designed to work with your digestion vials for a simple and automated solution. The COD kit ensures accurate and repeatable analysis by preparing and

19/11/2020 · The COD Test Tube produced by Aijiren is often used for chemical oxygen demand testing. The process is as follows: 2mL of water or fresh water sample is added to a 16mm glass culture tube containing digestion agent and catalyst. Cover the tube with a polypropylene lined polypropylene tube and heat it in a block digester at 150°C for 2 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. For higher concentrations the high range COD vials (0-1500 mg/L) should be used.
The HI94754B-25 are barcode reagent vials that follow the EPA approved method for the medium range determination of chemical oxygen demand (COD) using a compatible benchtop photometer. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each box for traceability.
