The methods specified are based on heating a portion of the test sample at a temperature of at least 1100 °C to 1200 °C in an oxygen atmosphere, passing the evolved oxidation products over a purification trap filled with manganese dioxide catalyst and silver permanganate catalyst (that oxidises CO to CO<(Index)2>), trapping the CO<(Index)>2, restoring the initial pH continuously by addition of hydroxyl ions either by potentiostatic titrimetry or by coulometry, or alternatively determining the CO<(Index)2> by IR absorption and integration of the signal obtained. Is applicable to the determination of 5 µg to 500 µg of carbon.
