Total organic carbon (TOC) analyzers are devices used to analyze the organic carboncontent in liquid as well as solid samples. They provide highly sensitive, non-specific readoutsof all TOC through two-stage processes involving oxidation and detection. Apart frommeasuring organic carbon, it can also detect Total Carbon (TC) and Total Inorganic Carbon(TIC) in solid and liquid samples.

Working principle:In the instrument, the sample is delivered to the combustionfurnace, which is supplied with purified air. There, it undergoes combustion through heatingto a high temperature (usually 680°C) with a platinum catalyst. It decomposes and is convertedto carbon dioxide. The carbon dioxide generated is cooled and dehumidified, and thendetected by NDIR (Non Dispersive Infrared) detector.

• TOC analyzers are used to evaluate the total amount of organic matter in water from the amount of carbon it contains.
• TOC analyzers are used in diverse fields, including the management of tap water, effluent, and ultrapure water, management of pharmaceutical water used in drug manufacturing processes, evaluation of cleaning efficiency (cleaning validation), and environmental investigations of river water and soils sample
