5220 CHEMICAL OXYGEN DEMAND (COD)* 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled con-ditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties, the dichromate ion (Cr2O7

For determination of low range Chemical Oxygen Demand (COD) by the Reactor Digestion method. US EPA approved for wastewater analysis using Hach Method 8000. Range: 3-150 mg/L COD. Pack of 150 vials EPA Approved Low Range (LR) and High Range (HR) vials are approved by the USEPA for NPDES reporting of wastewater COD concentrations. Simpler and Safer

Note: For best results, use the low range and ultra-low range vials for samples that have high chloride concentrations (near maximum concentration) and low COD concentrations. If sample dilution causes the COD concentration to be too low for accurate measurements, add 0.50 g of mercuric sulfate (HgSO 4) to each COD vial before the sample is added.
