Abstract
Rapid method was developed for determining the mass fraction of total carbon in boron carbide with a Vario El cube elemental analyzer (Elementar, Germany) intended for a CHNS analysis of organic and inorganic samples. The metrological characteristics of the suggested procedure were evaluated. The modification of the fluxing agent composition enabled a 1.5 times decrease in the time of oxygen dosing in oxidation of a sample, which substantially prolonged the service life of the reducing tube of the device. The key advantages of the suggested analytical procedure are the high rate of analysis and simplicity. The time required for a single analysis does not exceed 6 min.
