TOC Analyser for Cooling Water

The online analyser QuickTOCultra of LAR Process Analysers AG, Berlin, is a measurement system for the determination of the total organic carbon (TOC) in water. Using a horizontally and vertically moving injection needle the sample will be transported and injected form the sample vessel to the furnace. Due to the robust needle organic particulates within the sample will be considered within measurement reliably. Thus, sample filtration is unnecessary. A huge advantage when fresh water from surface water – where organic solids can occur - is used, since the sample is considered in its entirety. In the furnace, the sample is combusted at 1200°C. Due to the high temperature, the organic content is completely oxidized to CO₂. Hence, operators do not need expensive oxidation promoting catalysts. The entire TOC measurement cycle takes place in less than 3 minutes.

Due to its special construction design LAR's TOC analyser QuickTOCultra is optmially suited for every cooling water challenge. The analyser can measure up to six sample streams in one unit. Thus, the inlet and outlet of the cooling cycle can be monitored in one single TOC analyser. Differences in TOC that arise for example due to leakage or product spills are detected quickly. Thus, operators can take countermeasures to protect the cooling cycle as well as the environment.
