Carbon Analysis – How the Carbon Content of a Sample …

A key issue in carbon determination by this method is the purity of the Oxygen gas used. Typical impurities include CO 2 and CH 4 . CH 4 can be oxidised at the temperatures involved in the test to CO 2 + H 2 O, so for accurate results the effects of these impurities have to be resolved in the test method.
