Total organic carbon. TOC represents the total amount of organic matter present in the water. The concentrations present in water do not present any risk to health. No significant increase
Total Organic Carbon. A measure of the concentration of organic carbon in water, determined by oxidation of the organic matter into carbon dioxide (CO2). TOC includes all the carbon atoms covalently bonded in organic molecules. Most of the organic carbon in drinking water supplies is dissolved organic carbon, with the remainder referred to as particulate organic carbon. In natural waters, total organic carbon is composed primarily of nonspecific humic materials. Total organic carbon is used as a surrogate measurement for disinfection by-product precursors, although only a small fraction of the organic carbon will react to form these by-products. Quantitatively, total organic carbon is determined by removing interfering inorganic carbon, such as bicarbonate (HCO3–), and oxidizing the organic carbon to carbon dioxide. Typically, the carbon dioxide is then measured with a nondispersive infrared detector.
Total Organic Compound – is a direct measure of the organic, oxidizable, carbon based material in water. TOC is of concern in highly purified water used in electronic applications.
Total Organic Carbon - a measure of organic levels in ultrapure water. High TOC levels have been correlated with lower yields for semiconductors.
Total organic carbon test.
Total Organic Carbon - Organic matter plays a major role in aquatic systems. It affects biogeochemical processes, nutrient cycling, biological availability, chemical transport and interactions. It also has direct implications in the planning of wastewater treatment and drinking water treatment. Organic matter content is typically measured as total organic carbon and dissolved organic carbon, which are essential components of the carbon cycle. (credit referenced link)
Total Organic Carbon. TOC is the concentration of carbon present in oxidizable organic compounds in the water. It is expressed as ppm or ppb carbon.
Total Organic Carbon (water chemistry)
total organic carbon. This is the sum of organic carbon and is a monitoring parameter analyzed in environmental water programs. It is a physical sediment factor which can influence the concentration of other compounds. Represented variations in concentration can be attributable to spatial and temporal variations in sediment type.
Total Organic Carbon (considered the sorption phase for hydrophobic substances such as dioxin-like chemicals in sediments).
Total organic carbon. represents the total organic carbon in a given sample. Determined by oxidation of the organic matter with heat and oxygen or chemical oxidants, followed by the measurement of the H2O liberated with an infared analyser.
Total Organic Compounds. Gaseous organic compounds, including reactive organic gases and the relatively unreactive organic gases such as methane.
