PeCOD analysers accurately detect COD in samples from a variety of sources and overcome many of the problems encountered by existing COD methods. The core of the technology is the strong oxidation power which ensures complete oxidation of all oxidisable organic species in a simple and rapid fashion.

The patented PeCOD technology provides a unique nanotechnology-based photoelectrochemical technique capable of determining COD in natural and wastewater samples. It measures photocurrent charge originating from the oxidation of organic species contained in a sample to quantify COD. Tthis means the end user obtains a real measurement of organic pollution, not an inferred one.

• Real time results (less than 15mins ) to overcome the problems of time delays encountered by chemical oxidation methods
• Absolute COD measurement avoiding costly and time consuming regular calibration
• Complete oxidation leading to high accuracy and high reproducibility minimizing matrix variation problems.
• Direct signal acquisition resulting in high sensitivity and wide linear range
• Equivalent BOD
• No Hazardous reagents
• Small footprint & light weight less than 3.5kg makes it ideal for mounting on-line
• Splash resistant keypad
• Identical technologies across platforms (laboratory and on line unit) ensures consistency of results when switching between the two
• In line mixing avoids user intervention for difficult to analyse samples
• Unmatched ppb sensitivity (0.2 mg/l) and reproducibility (RSD=±3%)
