"total organic content" is a correct and usable phrase in written English.
You can use it when discussing the amount of organic material present in a given situation. For example, "The soil sample had a high total organic content, making it ideal for growing crops."
Three soil samples with a similar total organic content but with a different HC concentration (0.2, 1.0 and 6.5 g/kg) were compared in a microcosm experiment.
Through the analysis of controlling factors, the free gas production has no correlation with total organic content (TOC), shale desorption properties, or stress sensitivity of permeability.
The slope sediments and the ground ice contained therein have prominent relative maxima and minima in properties (grain size, total organic content, oxygen isotopes).
The studied samples have a total organic content (TOC) ranging from 1.4% to 1.82% and Tmax ranges between 472 °C and 529 °C.
The Lower Cretaceous shales of the Kharita and Alam El-Bueib formations exhibit good thickness, total organic content (TOC), kerogen type (mixed type II and III), and maturation.
The effects of initial Fe2+ and Fe3+ concentrations, [Fe2+/3+], type of iron salt (ferrous sulfate vs. ferric chloride), initial hydrogen peroxide concentration, [H2O2], on mineralization extent, i.e., total organic content (TOC) removal, were studied.
The relatively high (2 14%) total organic contents (TOC) of the kerogen-rich laminated micrites (KRLMs), which compose the 18-inch Layer and much of the remaining Middle Unit in the Fossil Butte Member, has been attributed anoxic to dysaerobic depositional environments [1], [3], [4].
The total organic carbon content and carbonate content identify differences in gross composition.
The total organic carbon content and the content of volatile solids (VS) of the substrates were determined.
Finally, the carbon-to-nitrogen ratio was determined by dividing the total organic carbon content to the total nitrogen content.
Total organic carbon content (TOC), black (soot) carbon content (BC), specific surface areas (SSA), and pyrene concentration of the whole sediments and particle size fractions are shown in Table 1.
