Total Organic Carbon Analyzer

SAE Technical Paper Series, 1991
<div class="htmlview paragraph">Development and testing of a high sensitivity monitor for the measurement of Total Organic Carbon (TOC) in water without gravity-dependent components and using minimal chemical reagents has been performed. A breadboard instrument was constructed and tested for linearity, selectivity, and day-to-day reproducibility.

Optimisation of a Photochemical Sensor for Total Organic Carbon Measurement

Annali di Chimica, 2005
AbstractA new tool for the measurement of TOC based on the heterogeneous photocatalysis activated by two different light sources has been planned. The instrument is constituted by a cell where the degradation occurs thanks to both the UV irradiation and the presence of a powered catalyst and by a measurement cell lodging CO2 gas permeable membrane ...

Total Organic Carbon Emissions From Municipal Incinerators

Waste Management & Research: The Journal for a Sustainable Circular Economy, 1987
Total carbon (TC), carbonate carbon (CC) and total organic carbon (TOC) were determined in bottom ash, filter dust and flue gas of Swiss municipal solid waste (MSW) incinerators. The highest TOC load was found in the bottom ash (2-3 g kg -1 MSW), followed by the filter dust (0.1-1.0 g kg

New Total Organic Carbon Analyzer

SAE Technical Paper Series, 1990
<div class="htmlview paragraph">The development of a high sensitivity, compact monitor for the measurement of total organic carbon (TOC) in water with no gravity-dependent components is discussed. The system is based on a combination of photo-catalzyed oxidation of organic compounds to form carbon dioxide, which is selectively measured using a ...

Organic-free water for total organic carbon determination

Analytica Chimica Acta, 1980
Abstract Commercially available “organic-free” water is compared with water cleaned by ultraviolet (u.v.) radiation for applicability to total organic carbon determinations. The u.v.-treated water contains an organic carbon concentration less than the detection limit of the method used (0.056 mg C l-1).
