Our LAR™ QuickCODlab™ 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.
Those who routinely perform laboratory tests for COD understand the standard COD method is an hours-long procedure using several hazardous substances. Fortunately, it is now possible to measure COD quickly, accurately, cleanly and safely in the laboratory, using high temperatures rather than chemicals to oxidize the sample. With the QuickCODlab, there is now a fast, reagent-free laboratory COD method. The same time-tested method used in the field for online monitoring is now available in a bench-top design. The QuickCODlab follows American Standard Method (ASTM D6238-98), using 1200°C instead of the standard 900°C, enabling chemical-free measurement.
With the QuickCODlab, complete measurements are made in only three minutes, with multiple measurements in only 10 minutes. This provides enormous time-savings compared to standard hours-long procedures.
We are the TOC Leaders™ in high-temperature TOC, COD, BOD and Toxicity water analysis for maximum reliability, high-performance and fast response.
COD measurement is accomplished in about 3 minutes. Thus, 3 replication measurements per sample can be determined within less than 10 minutes. The QuickCODlab offers enormous time and cost savings in comparison to standard procedures.
An O2 detector determines the oxygen used to digest all the constituents. The determination of the oxygen demand is performed over a wide variety of measurement ranges. The QuickCODlab also reliably measures the real COD in relevant measurement ranges from 5 to 100 mg/l.
The QuickCOdLAB easily masters salt concentrations of up to 10 g/l, and even up to 300 g/l of sodium chloride (NaCl) with the additional high salt option. The salts move through the oven and are carried out of the system together with the condensate finally being collected as solids in a special retaining device. This means that no salt residues can form in the oven and the sample does not have to be diluted, even at the highest of salt concentrations. This, in turn, having a positive effect on the accuracy of the measurements.
