. Using MicroVials for COD analysis is quick and easy. Chemical Oxygen Demand COD analysis is a measurement of the oxygen-depletion capacity of a water sample contaminated with organic waste matter. Similarly Chemical Oxygen Demand COD is the demand of oxygen required to reduce dichromate Cr 2 O 72 - Cr in 6 oxidation state to Cr 3.
Higher COD levels mean a greater amount of oxidizable organic material in the sample which will reduce dissolved oxygen DO levels.
