Summary:A method for determining degradable, organic carbon comprises the following steps: the sample is fed to a combustion tube along with a carrier gas; the sample is treated with inert gas in the combustion tube at at least 850° C.; the obtained pyrolysis gas, which contains the AOC, is conducted across a metal oxide as an oxygen donor for oxidizing purposes without adding oxygen; the AOC is oxidized while the metal oxide is reduced; the AOC is measured by means of a detector while the CO2 peak is detected, the carrier gas being switched from inert gas to O2 once the CO2 peak has passed; the RC is burned in the O2 atmosphere while the metal oxide is regenerated; and the RC is measured by means of a detector.
