Standard-Compliant Elemental Analysis of Silicon Carbide and Mixtures Containing Silicon Carbide by Combustion Analyzers

摘要

Elemental analyzers are important tools for quality control of a wide range of products. A variety of matrix materials, including ceramics, coal, steel or soil, can be analyzed to determine their element concentrations with different types of instruments. Eltra GmbH, located near Düssel-dorf, Germany, produces analyzers for C, H, N, S, O and thermogravime-try that perform standard-compliant determination of carbon in various chemical bondings, as well as oxygen and nitrogen in SiC and in materials containing SiC. The requirements that have to be fulfilled for a standard-compliant analysis may, however, vary greatly depending on the desired measurement parameters.
