Faster Accurate Results
PeCOD is the fastest available method for quantifying oxygen demand (OD), providing operators with real time data needed to make timely, impactful decisions that enhance environmental protection while generating substantial savings on chemical and energy use. It offers a low detection limit (< 1 mg/L) with results generated in less than 10 minutes.
Safe Green Chemistry
PeCOD offers a safe, fast and green chemistry method that can be used by anyone. This eliminates the need for trained analytical chemists on staff or an external lab facility. 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. 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 OD.
One Technology with Multiple Configurations
The PeCOD analyser is available in a variety of configurations that use the same innovative technology and method. PeCOD combines robust performance and flexibility to suit the needs of your laboratory or process operations.
