In 1946,Willard Libby (19081980) developed a method for dating organic materials by measuring their content of carbon-14,a radioactive isotope of carbon.The method is now used routinely throughout archaeology,geology and other sciences to determine the age of ancient carbon-based objects that originated from living organisms.Protein determination measuring protein content across Dec 23,2016 4 Techniques to Accurately Measure the Carbon Content in#0183;The three most common techniques used to measure protein content are Kjeldahl,Dumas (combustion),and NIR (near-infrared spectroscopy).While all three are valid,each of these methods comes with unique advantages or challenges.BUCHI Corporation is unique in that we have expertise in all three of these techniques.Monitoring Exhaled Carbon Dioxide Respiratory CareIntroduction.The measurement of CO 2 in air was first developed around 1918 and performed to analyze gas concentrations in mines.1 This process of analysis was painstakingly tedious,using an intricate apparatus that involved measuring quantities of CO 2 and other gases that were chemically absorbed from a known gas volume.The volume of absorbed CO 2 was then compared with the total gas

Methods for the Determination of Total Organic Carbon

In conjunction with the quantitative or semi-quantitative methods,there are also methods that are qualitative and can accurately identify the type of carbon compounds (e.g.,sugars,carbohydrates,lignin,etc.) in the sample but are not far enough along in their development to quantitate the carbon content of the sample.Methods for the Determination of Total Organic CarbonIn conjunction with the quantitative or semi-quantitative methods,there are also methods that are qualitative and can accurately identify the type of carbon compounds (e.g.,sugars,carbohydrates,lignin,etc.) in the sample but are not far enough along in their development to quantitate the carbon content of the sample.Measuring and reporting soil organic carbon Agriculture Using a measure of bulk density the amount of carbon per hectare in a given depth of soil can be calculated as shown.Calculation.The amount of organic carbon to 10cm depth in soil with a carbon value of 1.5% and bulk density of 1.3g/cm 3 is 15 (g C/kg soil) x 1 300 000 (kg soil/ha) = 19.5t C/ha or 1.5 x 1.3 x 10 = 19.5t C/ha.Adjusting for
