The world’s fastest method for chemical oxygen demand (COD) analysis is also available in a portable field unit. Just add the battery and carrying case and COD can be measured in the field without the need to transport toxic or hazardous reagents.
- Small footprint (508 x 355.6 x 609.6 mm, 20 x 14 x 24 in)
- Convenient case with wheels (weighs approximately 16 kg, 35 lb with analyzer & supplies)
- No sample digestion is required, making it a truly portable technique
- MANTECH’s PeCOD Pro™ software adds automation and a sleek user interface
MANTECH’s revolutionary PeCOD® COD Analyzer technology provides accurate chemical oxygen demand (COD) results in 15 minutes — without the use of harmful chemicals including dichromate and mercury. Highly adaptable for wastewater and drinking water applications, the PeCOD® COD Analyzer’s patented nanotechnology-based approach to COD analysis will save you time and money while protecting the environment and the health and safety of your workers.
peCOD is the fastest available method for quantifying chemical oxygen demand (COD), 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.
peCOD nanotechnology provides a higher oxidizing power and none of the risks associated with harmful chemicals such as dichromate and mercury used in traditional COD analysis. It’s safe and simple to use for any laboratory or operations staff member at any point in the process.
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 COD.
The PeCOD® COD Analyzer technology is a proven performer in a variety of municipal and industrial wastewater applications. Recent studies have shown a strong correlation between the 15 minute peCOD method for testing chemical oxygen demand (COD) and standard dichromate COD (CODCR) and five-day BOD (BOD5) methods. In most cases, peCOD can be used as a BOD screening tool, providing accurate BOD estimates in just minutes versus several days.
The PeCOD® COD Analyzer will be the technology of choice as new regulations take effect in Europe in September 2017 that will eliminate the use of dichromate in COD testing. peCOD conforms to Method E3515, released in 2014 by the Ontario Ministry of Environment and Climate Change (MOECC) to replace the dichromate method for COD testing. peCOD is also included as an approved alternate COD method in the Protocol for the Sampling and Analysis of Industrial/Municipal Wastewater which was updated in 2016 by the MISA (Municipal Industrial Strategy for Abatement) program.
The PeCOD® COD Analyzer 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.
MANTECH is excited to announce that the release of the PeCOD L50 Model! See here for more details.
The L50 is a direct replacement for the L100 shown in previous videos and pictures. The L50 offers a simpler, industrial and robust design, with improved pricing over the L100. Contact us for more information.
The PeCOD® COD Analyzer is available in laboratory, portable and online configurations that are highly customizable. The peCOD system can be configured to accommodate laboratory operations, automated sampling, or continuous process monitoring.
