The sample is bunned in an oxygen stream using induction heating and the carbon dioxide in the evolved gases is absorbed by a dilute sodium hydroxide solution. The amount of carbon present in the sample is determined by measuring the change in conductance of the absorbing solution and by comparing this change against a standard curve. The method covers the deterrnination of carbon in zirconium and Zircaloy in a concentration range from 10 to 800 ppm on a 0.5-g sample basis. Satisfactory results may be obtained on sample portions as low as 0.1 g, thus extending the upper limit to 4000 ppm carbon. Sample segregation must be taken into consideration whenever smaller samples are used. (auth)
