Abstract

PURPOSE: To analyze with good reproducibility by a simple device easy in hadling by heating metal sample in oxygen to make carbon in the sample CO2, introduce the mixed gas current of CO2 and O2 to an oxygen concentration cell and integrating by time the voltage thereof.
CONSTITUTION: A ceramic burning boat containing a metal sample 1 of a predetermined amount is charged into a portion of a heating furnace 3 of a ceramic burning pipe 4 and oxygen gas from an oxygen feed pipe 5 is fed. The sample 1 is heated to burn carbon in the sample, the produced CO2 is mixed into the oxygen gas current and this mixed gas current is fed to the oxygen concentration cell from the sample gas feed pipe 14 through an exhaust pipe 6. In the oxygen concentration cell, the temperature of the electrolytic pipe 11 is maintained at a fixed one by the heating furnace 16 and voltage generated by the difference between the partial pressure of oxygen of the sample gas outside the electrolytic pipe 11 and an internal reference oxygen partial pressure is integrated by time to obtain the content of carbon.
