TOCmåling

TOCmåling refers to the measurement of Total Organic Carbon (TOC) in a sample. TOC is the total amount of carbon bound in organic compounds. It is a key indicator of water quality and is used to assess the level of organic contamination in various water sources, including drinking water, wastewater, and surface water. The presence of high levels of TOC can indicate pollution from industrial, agricultural, or domestic sources.

The measurement of TOC is typically performed using specialized analytical instruments. The most common method involves the oxidation of organic compounds to carbon dioxide (CO2), which is then detected and quantified. This oxidation can be achieved through various techniques, such as high-temperature combustion, UV-persulfate oxidation, or a combination of both. The resulting CO2 is measured using a non-dispersive infrared (NDIR) detector.

TOC analysis provides a comprehensive measure of organic pollution, unlike other methods that might only detect specific organic compounds. It is a valuable tool for environmental monitoring, water treatment process control, and research. By understanding the TOC levels, scientists and engineers can make informed decisions about water management, pollution control, and the effectiveness of treatment processes. Low TOC levels are generally desirable for potable water, while wastewater treatment aims to significantly reduce TOC before discharge.
