Total Organic Carbon (TOC) Measurement

TOC Analyzers, Meters, Testing, Analysis and Measurement

What is a Total Organic Carbon (TOC) Analyzer?

TOC analyzers measure the amount of organic compounds contained in a water sample. Organic carbon-containing compounds can either be dissolved in water or exist in water as undissolved, suspended material, or liquid. This organic matter can enter water naturally and through man-made sources/processes.

Examples of organic matter are plant or animal based or synthetic substances containing carbon and other elements defining organic compounds. Inorganic matter is comprised of mineral compounds that may or may not contain carbon.
