The HI-94754A-25 are barcode reagent vials that follow the EPA approved method for the low range determination of chemical oxygen demand (COD) using a compatible benchtop photometer. These high quality reagents are clearly marked with the lot number and expiry date on each box for traceability.

THEORY 2.1 Dissolved Oxygen (DO) All gases of the atmosphere are soluble in water to some degree. Oxygen is classified as poorly soluble, and its solubility is affected both by atmospheric pressure, and physical and chemical properties of water such as temperature, salinity, pollutants, etc. The solubility of atmospheric oxygen in fresh waters

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

Chemical oxygen demand. In environmental chemistry, the chemical oxygen demand ( COD) is an indicative measure of the amount of oxygen that can be consumed by reactions in a measured solution. It is commonly expressed in mass of oxygen consumed over volume of solution which in SI units is milligrams per litre ( mg / L ).

Chemical Oxygen Demand (COD) COD is an indirect measure of the total organic matter widely used for wastewater monitoring, design and operation of STPs. It consists of the amount of oxygen required for the organic matter to be oxidized by a chemical oxidant (usually potassium dichromate in acid medium). The sample is digested for 2 h at 150°C.
