Total organic carbon analysers (known as TOC analysers) are devices designed to determine the carbon content of a sample, excluding CO₂ and other impurities. In TOC analysers, the method of catalytic oxidative combustion at high temperatures (up to 720°C) is used to convert organic carbon into CO₂. The CO₂ concentration is measured using a specialised sensor. These devices are capable of determining carbon concentrations across an extremely wide range (from 4 µg to 30,000 mg/l). TOC analysers are also capable of determining the concentration of inorganic carbon in solutions of CO₂ and acidic salts containing carbon.
