The new QuickCODlab laboratory analyser from LAR Process Analysers AG determines chemical oxygen demand (COD) without chemicals. The high-temperature method used has proven itself in online analytics for many years and has now been optimised for laboratory use. The sample is injected directly into the furnace using a precision syringe. Optionally, an autosampler is available for up to 60 samples. The sample is then completely oxidised at 1,200 °C. Hence, oxidation-promoting chemicals can be dispensed with. In addition, the measurement results are free from chloride interference. The amount of oxygen needed for the complete combustion is defined by an oxygen detector. The measurement is carried out in 1-3 minutes, offering a fast and cost-effective analysis. The COD laboratory analyser is characterised by a high operational safety and low cost of ownership.
