Micro Chemical Oxygen Demand System Titration Method Scope and Application 1.1 The Chemical Oxygen Demand (COD) test determines the quantity of oxygen required for oxidation of reduced species including using a 1.2 9
Chemical Oxygen Demand The Hanna COD method is based on the well-established closed dichromate-reflux colorimetric method. The colorimetric measurement of COD is faster and easier to perform than the titrimetric analysis and do not require additional reagents.
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). A COD test can be used to easily quantify the amount of organics in water. The most common application
Details of Chemical Oxygen Demand Test: 2mL of a water or waste water sample are added to a 16mm glass culture tube containing the digestion reagent and a catalyst. The tube is capped with a polypropylene, PTFE lined cap and heated in a block digester at 150C for 2 hours.
2018/06/13 · Vials were sealed with FluroTec ®-laminated elastomeric closures under ambient conditions and tested for seal integrity to ensure the crimping process was successful prior to placement in a cryogenic storage chamber for 8 days.
