organic carbon calculations

This method for determining total organic carbon (TOC) indirectly measures the total amount of organic substances present in water for pharmaceutical use. The molecules of organic matter in water are oxidized to produce carbon dioxide which is then measured in an instrument and from the result, the concentration of carbon in the water is ...

This calculator asks the question: "If I want to change my Total Organic Carbon value by 0.05%, 0.1% or 1.0%, how much plant biomass do I require to do this?" We encourage you to vary the default numbers that already appear in the white boxes to see how this changes the biomass required for a change in total organic carbon (TOC).

Total organic carbon (TOC) is the amount of carbon found in an organic compound and is often used as a non-specific indicator of water quality or cleanliness of pharmaceutical manufacturing equipment. TOC may also refer to the amount of organic carbon in soil, or in a geological formation, particularly the source rock for a petroleum play; 2% is a rough minimum.

Mar 28, 2017· Total organic carbon (TOC) is the amount of carbon found in an organic compound and is an important sum parameter for accessing the organic load of water. As all organic carbon compounds are determined and specified in terms of carbon mass, TOC is an exactly definable absolute quantity and is directly measurable (unit: mg/L C).

The quantity of organic carbon is relative to the total organic carbon (TOC) content of rocks. Thus, TOC is the concentration of organic matter in the rocks and is expressed by the weight percent of organic carbon. A value of about 0.5% TOC by weight percent is considered a minimum or threshold for an effective source rock.

While the actual measurement of oxidisable Organic Carbon, the data are normally converted to percentage organic matter using a constant factor, assuming that organic matter contains 58% Organic Carbon. However, as this proportion is not in fact constant, we prefer to report as oxidisable Organic Carbon, or multiplied by 1.334 as Organic Carbon.
