The PeCOD\u00ae COD Analyzers<\/strong> from MANTECH<\/strong> enable the determination of chemical oxygen demand (COD) within less than 10 minutes<\/strong> \u2013 entirely without the use of dichromate or mercury. The patented photoelectrochemical measurement technology delivers fast, accurate, and reproducible results for wastewater, drinking water, and process water analyses.<\/p>\n

Unlike classical dichromate methods, the time-consuming sample digestion reaction is eliminated. This significantly reduces analysis time, operating costs, and the handling of hazardous chemicals.<\/p>\n

The PeCOD\u00ae technology is based on a patented photoelectrochemical measurement principle. The heart of the system is a TiO\u2082 nanoparticle sensor, which is activated by UV light. Organic compounds are oxidized on the sensor surface, and the resulting electrical current serves as a direct measure of the chemical oxygen demand of the sample.<\/p>\n

Unlike the traditional dichromate method, this method requires neither hazardous oxidizing agents nor a sample digestion reaction lasting several hours. As a result, measurement results are available within just a few minutes, enabling rapid process monitoring and immediate responses to changes.<\/p>\n

The complete oxidation of organic matter ensures high measurement accuracy over a wide concentration range. Studies also show a very good correlation of PeCOD\u00ae results with both the classical CODCr method and biochemical oxygen demand (BOD\u2085), allowing PeCOD\u00ae to be used as a rapid screening tool.<\/p>\n

Available Systems<\/h2>\n

The PeCOD\u00ae product family is available in several versions:<\/p>\n

PeCOD\u00ae L50 Laboratory Model<\/h3>\n

Compact benchtop device for laboratories in industry, government, and research. The system offers a small footprint, simple operation, and expansion options for automated sample feeding and additional measurement parameters.<\/p>\n

PeCOD\u00ae L50 Portable<\/h3>\n

Portable COD analysis system for field use. Thanks to its battery-powered operation and carrying case, COD measurements can be performed directly on site\u2014without having to transport hazardous reagents.<\/p>\n

PeCOD\u00ae Online L50<\/h3>\n

Online system for continuous process monitoring. The device can be connected directly to process lines and automatically handles filtration, purification, calibration, and analysis. Integration into SCADA systems enables permanent real-time monitoring of COD values.<\/p>\n

Automated Systems<\/h3>\n

For high-throughput laboratories, MANTECH offers automated PeCOD\u00ae systems with autosamplers for unattended operation.<\/p>\n
