Chengdu Huacheng Instrument Co., Ltd., a leading provider of environmental instruments and new energy testing equipment solutions in China, has introduced the PeCOD analyzer for COD, BOD, and NOM analysis. The PeCOD analyzer offers a simple, fast, and accurate solution for the analysis of COD, BOD, and NOM in wastewater.
COD, BOD, and NOM are important parameters that are used to assess the quality of wastewater. COD (Chemical Oxygen Demand) measures the amount of oxygen required to oxidize all the organic and inorganic compounds in the water. BOD (Biochemical Oxygen Demand) measures the amount of oxygen required by bacteria to biodegrade the organic material in the water. NOM (Naturally Occurring Organic Matter) is a complex mixture of organic compounds that are present in natural waters and can contribute to the formation of disinfection by-products and other water quality concerns.
The PeCOD analyzer uses a powerful oxidation reaction to measure COD and BOD in just a few minutes. The oxidation reaction is based on the principle that organic matter in water reacts with a strong oxidant, such as persulfate, to produce carbon dioxide. The amount of carbon dioxide produced is directly proportional to the amount of organic matter in the water. The PeCOD analyzer also measures NOM by using a UV absorption method that is based on the fact that NOM absorbs UV light at specific wavelengths.
The PeCOD analyzer offers several benefits over traditional methods of COD and BOD analysis. Firstly, it is a faster method that can provide results in just a few minutes. This is in contrast to traditional methods, which may take several hours or even days to produce results. Secondly, the PeCOD analyzer is a simpler method that requires less sample preparation and equipment. Traditional methods require extensive sample preparation, such as dilution, filtration, and addition of chemicals, which can be time-consuming and increase the risk of error. The PeCOD analyzer requires minimal sample preparation and can be operated with just a few simple steps.
Lastly, the PeCOD analyzer is a more accurate method that produces consistent and reliable results. Traditional methods of COD and BOD analysis are prone to interference from other substances in the water, which can lead to inaccurate results. The PeCOD analyzer uses a patented photocatalytic oxidation method that is highly specific to organic matter and does not react with other substances in the water. This produces accurate and precise results that are not affected by sample matrix effects.
In summary, the PeCOD analyzer is a simple, fast, and accurate solution for COD, BOD, and NOM analysis in wastewater. It offers several benefits over traditional methods of analysis, including speed, simplicity, and accuracy. Chengdu Huacheng Instrument Co., Ltd. is proud to offer this innovative solution to its customers and looks forward to continuing to provide cutting-edge solutions for environmental analysis and testing.
