Analysis of COD is commonly used in environmental analysis. The analysis is often time consuming and chemicals such as mercury and dichromate, which are harmful to environment, are being used.

PeCOD (Photo Electric Cemical Oxygen Demand) from Mantech is a patented way of getting analysis of COD done quickly and with no use of harmful chemicals. In only 15 minutes a result of COD will be produced. The quick analysis will almost give operator a real time analytical results, which can be used for changing treatment at the plant. The core of the PeCOD is the sensor which consist of UVactivated nano particles of titanium dioxid. The PeCOD can be used as portable, bench top, automated or online instrument.
