COD versus BOD Like BOD, chemical oxygen demand (COD) can be used to estimate the amount of organic loading in a water sample. COD describes the amount of oxygen required to chemically breakdown the pollutants, while BOD indicates the amount of oxygen required to breakdown the pollutants, biologically with microorganisms.
Turbidity, a measure of cloudiness in liquids, has been recognized as a simple and basic indicator of water quality. It has been used for monitoring drinking water, including that produced by filtration for decades. Turbidity measurement involves the use of a light beam, with defined characteristics, to determine the semi-quantitative presence
To clean BOD bottles, use a 20 to 50% sulfuric acid solution (approximately 5 to 14 N), or for maximum cleaning use a chromic acid cleaning solution. Pour several mL of the acid into each bottle, cap, and invert to coat the inner surfaces of the bottles. Rinse thoroughly with distilled water.
Shell vials are an economical choice for many routine HPLC applications. These neckless vials with inserts are sold as kits including polyethylene push in caps to assure proper fit and function. Vial selections include clear glass, amber glass or polypropylene
