Understanding TOC measurement techniques is crucial if you're involved in water quality assessment or industrial process control. TOC is a fundamental parameter used to quantify the amount of organic content present, which directly indicates water quality. Here, we delve into the significance of TOC analysis, the different methods of measurement, and their applications.
Total organic carbon analysis provides essential insights into the organic content present in a sample. It aids in identifying organic pollutants, monitoring water quality changes, and ensuring compliance with regulatory standards. By measuring TOC, scientists, engineers, and process owners can better understand the quality of their water systems, leading to informed decision-making and sustainable practices.
The concentration of organic compounds in a water sample is determined through TOC measurements. These organic compounds cannot be detected through conductivity measurements since they are non-conductive. To detect these compounds, they must be converted into a form that can produce conductive species in pure water. This is done through oxidation, which generates carbonic acid, a conductive species. The conductivity of the resulting carbonic acid is then measured and used to determine the level of organic contamination in the water.
To determine TOC levels, organic compounds must undergo oxidation using various methods available today, including:
The TOC analysis method is used in various industries, such as pharmaceuticals, semiconductors, and power. Specifically, in the pharmaceutical industry, TOC analysis is applied in numerous ways, including monitoring the quality of water used for purified water and water for injection. In the semiconductor industry, TOC measurement is utilized to monitor the quality of water used during wafer manufacturing. The power industry also relies on TOC measurement to monitor water quality in the water/steam cycle.
