4 principle of the method
The samples were high temperature combustion or acid treatment, the appropriate form of carbon is converted to carbon dioxide, generated by the sample and the sample of
Proportional to the carbon content. An oxygen carrier, the content of carbon dioxide to form carbon content is calculated corresponding measured by an infrared detector.
TOC can be used directly or subtraction method was measured.
4.1 Determination of total organic carbon subtraction
4.1.1 Determination of total carbon
Samples from the injector into the combustion temperature, which leads to high purity oxygen in the sample of all carbonaceous material is oxidized to carbon dioxide, produced by
