Abstract The applicability of an automated Dumas-GC method for the determination of nitrogen and carbon in refractory materials was investigated. Analyses were carried out to determine nitrogen and carbon in TiN, ZrN and Ti(C,N) using CuO, V2O5 and Pb3O4 as oxidizing additives. The reproducibility of the analyses obtained with V2O5 was better than ± 1 rel% for major constituents. An estimation of the accuracy of the Dumas-GC method shows that this rapid and low-cost method can compete with other methods, at least for the refractory nitrides and carbonitrides of the transition metals.
