Chemical composition of oxides varies during production depending on process parameters. Depending on precursor materials and furnace atmosphere, e.g. carbon and oxygen concentrations are changed. Elemental analysis is the ideal analytical method to exactly monitor light elements like carbon, oxygen, nitrogen and hydrogen not only during production but already at development stages. Our inductar series is made for easy and accurate analysis of these elements, which are subject to changes during thermal processing. Thus, high performance ceramics are ensured by detailed composition control during both R&D and production as well.
