TOC COD BOD Online Water Analysis
TOC COD BOD Online Water Analysis
High Temperature Method for Reliable Online Water Analysis Technology
Total Organic Carbon (TOC) is a measure of the amount of carbon-containing organic compounds present in water. High-temperature methods for detecting TOC in water involve the complete oxidation of organic compounds in a water sample at high temperatures, followed by the measurement of the resulting carbon dioxide (CO2) released.
Our LAR™ water quality analyzers use a high temperature method of 1,200°C, can completely oxidize a sample to accurately determine sum parameters – particularly when measuring the TRUE TOC with differing of concentrations. LAR is your solution for the determination of parameters such as TOC, TNb, TOD, COD, BOD and toxicity. We are the only company worldwide that, using a high temperature method of 1,200°C, can completely oxidize a sample to accurately determine sum parameters. Particularly when measuring the TRUE TOC with differing of concentrations.
For an exact TOC measurement, all carbon bonds must be reliably combusted. Using a temperature of 1,200°C, we have developed a high temperature method which makes this possible! This temperature was chosen due to the proven fact that a complete oxidation of a sample cannot occur at temperatures below it. For example, the carbon bonds of carbonates only break fully when reaching a combustion temperature of 1,200°C. Basically, the lower temperatures deliver less exact measurement results. For this reason, we describe this as TRUE TOC. Because of our high temperature capability, our analyzers do not require any catalysts. Catalysts are only necessary for the low temperature catalystic “high temperature” oxidation (680 – 1,100°C) to support the oxidization of the carbon bonds. However, the performance of the catalysts is lowered over time. This affects the measurement, necessitates continual new calibration, and eventually requires that the catalysts be replaced.
