  • New application notes published for the PeCOD Chemical Oxygen Demand (COD) Technology

    Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) are important diagnostic parameters for the determination of water quality in natural waterways and waste streams. The standard BOD test requires five days to complete, and is therefore unable to provide continuous monitoring of organic load. COD is therefore often used for BOD screening. The PeCOD method for COD analysis is a new ...
