Multiphase carbon determinator, C,Corg

Method description

The LECO RC612 multiphase carbon determinator quantifies the carbon content present in the sample and identifies the source of several types of carbon content. During combustion of the sample in an oxidizing atmosphere all forms of carbon (except some carbides) are converted to CO2. In contrast organic forms of carbon produce both H2O and CO2. Thus the presence of organic carbon may be verified by finding coincident peaks in H2O and CO2. A ramping temperature program can be used to indicate the temperatures at which the differing forms of carbon are oxidized, thereby enabling the the operator to distinguish between different carbon sources (organic, inorganic and partly elementary carbon). Infrared detection is used to quantify the result as a weight percentage.
