Chemical oxygen demand (COD) analyzer for government and academic solutions - University / Academia / Research
PeCOD® is the only Chemical Oxygen Demand (COD) analysis technology to use the powerful UV-activated nanoparticle TiO2 (titanium dioxide) photocatalyst which is at the core of the system. The high electrochemical potential of the TiO2 gives it a substantial advantage over the modest chemical potential generated by the dichromate method. 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 broader 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 only choice when health and safety is a priority
Laboratory staff have known for a long time about the potential negative health impacts and safety dangers of the standard “dichromate method” for COD analysis, even the European Union REACH regulation has banned dichromate effective 2017. Any level of dichromate, no matter how it is packaged or handled, still represents a danger. PeCOD® does not use harmful dichromate for COD analysis. Leading laboratories are converting to PeCOD® COD analysis to protect the health and safety of their staff, students and the environment.
PeCOD®COD technology is used around the world in a wide variety of settings, including:
- College laboratories
- University laboratories
- Government Enforcement Agencies
- Government Regulatory Agencies
