Fast, green, accurate Chemical Oxygen Demand analysis. Using a nanotechnology based approach, the PeCOD® analyzer obtains fast BOD/COD results without the use of harsh chemicals, such as dichromate and mercury. Ideal for real-time monitoring for quicker and more informed decision making.


The water quality monitoring system that is fast, accurate, easy-to-use and does not use dichromate.

The PeCOD® approach measures photocurrent charge originating from the oxidation of organic species contained in a sample to quantify COD.
The result is that the user obtains the most accurate measurement of organic pollution, in less than 15 minutes, with no use of dichromate or other hazardous chemicals.

PeCOD® is the fastest available method to quantify COD from a wide variety of waste streams, offering users unparalleled access to accurate information to make impactful process control decisions.
COD analysis simply requires pushing the “run” button and the COD result is displayed in just a few minutes, making COD analysis simple and safe for all operations staff to use.

Operators no longer have to undertake potentially hazardous operations such as digesting samples with boiling sulphuric acid containing dichromate, mercury and silver salts (the “dichromate method” of COD analysis).
PeCOD® makes the laboratory a safer place to work, by eliminating the use of toxic and hazardous reagents in COD analysis.
PeCOD® COD analyzer systems are used around the world and trusted by government regulatory agencies, national laboratories and universities, industrial sites, food & beverage facilities and municipal wastewater facilities.
