COD Analyser for Waste Water Analysis
Mar 24 2015
LAR's QuickCODultra is an online COD analyser for the determination of the chemical oxygen demand (COD) in complex water. The analyser uses a robotic horizontally and vertically moving injection needle. It enables the injection of the raw waste water sample incl. particulates into the oven. Thus, operators do not need any sample preparation such as filtration. The COD analyser works with a high temperature combustion method at 1200 °C. At this temperature all compounds are fully oxidised. As a result, measurement results are free of chloride interferences and operators do not need expensive oxidation promoting catalysts. The amount of oxygen needed is detected by an oxygen detector. The determination of the chemical oxygen demand takes place in less than 2 minutes. Using the muti-stream option the QuickCODultra measures up to 6 sample streams in one unit.
LAR's 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.
