Abstract
An apparatus for analyzing carbon in metals, in which a metallic sample is burned in a current of oxygen in a combustion furnace and the concentration of carbon contained in the metallic sample is calculated from the total concentration of carbon monoxide and carbon dioxide in the gas generated in the combustion furnace, the concentration determined by means of a non-dispersive infrared analyzer. The non-dispersive infrared analyzer is provided with a detector which exhibits almost the same sensitivity to both carbon monoxide and carbon dioxide.
