Our LAR™ QuickCODultra™ online COD water analyzer is a high-performance analyzer that measures the chemical oxygen demand (COD) of water samples. To measure the real oxygen demand, the QuickCODultra water analyzer utilizes a UV-activated persulfate digestion method that ensures complete oxidation of all organic compounds in the sample, including difficult-to-oxidize compounds such as humic acids and lignin. The analyzer then measures the amount of oxygen required for this oxidation reaction and calculates the COD value.
Our LAR™ QuickCODlab™ online COD water analyzer is the most reliable measurement system for the determination of the chemical oxygen demand in laboratories. Using this environmentally friendly COD analyzer and analysis technique, you can now determine chemical oxygen demand quickly, cleanly and safely – without any chemicals. Chemical oxygen demand (COD) is one of the most important sum parameters in water analysis. It is considered as a reference for the organic load of wastewater, both in the industrial and municipal sectors. In general, analytical processes are based on the use of different reagents. However, the safe and environmentally friendly procedure is thermal oxidation.
The COD value indicates the amount of oxygen consumed during the oxidation of organic substances of a water sample. The standard COD procedures are subject to criticism, due to their high consumption of hazardous chemicals, so a reliable COD measurement system needs to be environmentally friendly and free of chloride interference. Our analyzer uses a temperature of 1,200°C which guarantees complete combustion and eliminates the need for chemicals. The QuickCODlab precisely determines the COD within minutes.

CONTINUOUS COD WATER ANALYZERS FOR LABORATORIES.
By measuring the COD value, the QuickCODultra onlne COD water analyzer can determine the real oxygen demand of the sample, which is a measure of the amount of oxygen required to oxidize the organic matter present in the sample. This information is useful for a wide range of applications, including monitoring wastewater treatment processes, assessing the quality of drinking water, and evaluating the environmental impact of industrial processes.
QuickCODultra online COD water analyzer uses thermal combustion to get results within minutes, even with difficult sample matrices like sewage treatment and industrial wastewater applications. It is best suited for: plant effluent monitoring, wastewater treatment (influent and effluent water), detection of organic spills and product loss (e.g. in chemical, petrochemical and food processing plants). Combustion at 1200°C guarantees the complete oxidation of the sample. Even loads with salt concentration of up to 20% and in the case of NaCl as much as 30%, are easily melted at this temperature. No disposal is needed for analysis residue, cleaning solutions or harmful reagents.
