The revolutionary technology of the MANTECH PeCOD Analyzer provides accurate chemical oxygen demand (COD) results in just 15 minutes. No need to use harmful chemicals such as dichromate and mercury. Highly suitable for wastewater and drinking water applications, the PeCOD COD analyzer’s patented nanotechnology-based approach will save you time and money while protecting the environment and the health and safety of your workers. PeCOD is available in several configurations: Benchtop, Portable, Automated and Online.



Fast and accurate results

PeCOD is the fastest method to quantify chemical oxygen demand (COD). It provides the data needed to take corrective action in just 15 minutes while reducing the costs associated with the use of oxidizing chemicals.

Oxidizing power without chemicals

The TiO2 (titanium dioxide) nanoparticle photocatalyst in the PeCOD analyzer provides higher oxidizing power and eliminates the risks associated with the use of harmful chemicals such as dichromate or mercury used in traditional COD analysis. It is safe and easy to use.

With this patented technology, the oxidation potential of TiO2 ensures that virtually all organic matter will be fully oxidized, resulting in a true COD measurement.

PeCOD and BOD5 measurement

The PeCOD analyzer has proven itself in various municipal and industrial wastewater analysis applications.
Recent studies have shown a strong correlation between the PeCOD method, which provides results in 15 minutes, and BOD5 (biochemical oxygen demand measured after 5 days).

In many cases, PeCOD can be used as an aid to assess the BOD5 value.
