Iso9001 chemical oxygen demand vials

2019/09/18 · Chemical oxygen demand (COD) is the amount of a specified oxidant that reacts with the sample under controlled conditions. Results are defined as the mg of O 2 ‚ consumed per liter of sample. The sample is heated for two hours with a strong oxidizing agent, potassium dichromate (Cr 2 O 7 2- ).

Vials contain premeasured digestion reagents suited to your expected range of COD, so there is no measuring of harmful chemicals- simply add your sample to the vial and digest. Caution: The vials contain hazardous chemicals, typically corrosive, acute

2018/08/08 · The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater. The contamination level is determined by measuring the equivalent amount of oxygen required to oxidize organic matter in the sample.
