The QuickCODultra online analyser from LAR Process Analysers AG is especially designed for chemical oxygen demand (COD) measurements in water. Inside the analyser, the sample is transported and injected to the furnace using a robotic, horizontally and vertically moving injection needle. Sample pretreatment or dilution is not required. In the furnace, the raw water sample is completely oxidised at 1,200°C. Then, the amount of oxygen needed is detected by an oxygen detector. Due to the high oxidation potential of the 1,200°C no oxidation-promoting catalysts or hazardous chemicals are needed. As a result, the costs of ownership are minimized. Moreover, the measurement results are free of chloride interferences. The determination of the chemical oxygen demand takes place in less than 2 minutes, enabling operators a fast and environmentally friendly opportunity for the measurement of COD. The COD analyser is optimally suitable for the detection of production losses in chemical and food industries as well as for control of waste water treatment plants.
