E4F - C Organic (calc)

The C-Organic is calculated according to the following:

C-Organic = Total C – CCO2 – CGraphitic

Carbon analysis is performed by the absorption of IR energy which can be attributed only to carbon dioxide (CO2) which absorbs IR energy at a precise wavelength within the IR spectrum. The concentration of CO is detected as a reduction in the level of energy at the detector. It can be measured in either an inert atomsphere or an oxygen atmosphere (binding carbon species with the oxygen to form CO(converted to COprior to detection) and CO2, the majority being CO2 ,and is measured as carbon dioxide in the IR cell as gases flow through the IR cells. Energy from the IR source is absorbed as the gas passes through the cell, preventing it from reaching the IR detector.  All other IR energy is prevented from reaching the IR detector by a narrow bandpass filter. Because of the filter, the absorption of IR energy can be attributed only to carbon dioxide (CO2). The concentration of CO2 is detected as a reduction in the level of energy at the detector.
