About the PeCOD® Analyzer Technology

The PeCOD® Analyzer is a patented technology that directly measures photocurrent/charge originating from the oxidization of the organic contamination in a test sample.

The core of the technology is the PeCOD sensor, which consists of a UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst coupled to an external circuit. The high electrochemical potential of the TiO2 gives it a substantial advantage over the modest chemical potential generated by the dichromate method.

When a sample is introduced into the microcell containing the PeCOD sensor, the TiO2 is irradiated by UV light, and a potential bias is applied. The UV light creates a photohole in the TiO2 sensor with a very high oxidizing power and organics in the cell are oxidized.

PeCOD is extremely accurate across a broad range of organics. The powerful oxidizing potential of UV-illuminated TiO2 ensures that virtually all species will be fully oxidized giving a true measure of COD.

The PeCOD® Analyzer is highly adaptable and has both wastewater and drinking water applications.
