Total organic content test

WebAug 28, 2024 · The total organic carbon content for a variety of different samples can be determined; there are very few samples that cannot be measured for total carbon content. Before treatment, a sample must be homogenized, whereby a sample is mixed or broken such that a measurement done on the sample can be representative of the entire sample. WebPut the soil in a fan set to a low temperature (60-80 o C) for 4-6 hours. Sandy soils will dry more quickly than clayey ones. Remove the soil and tray carefully from the oven using heatproof gloves and leave somewhere dry to cool. Calculate the weight of the dry soil D – A (weight of dry soil and tin – weight of tin).
