CATALYTICALLY ACTIVE COMPONENT FOR THERMAL IONIZATION DETECTORS FOR THE DETECTION OF HALOGEN-CONTAINING COMPOUNDS AND PROCESS FOR PRODUCING AN OXIDE-CERAMIC MATERIAL FOR THE COMPONENT

摘要

The invention relates to catalytically active components having an improved microstructure for thermal ionization detectors for the detection of halogen-containing compounds and also a process for producing an oxide-ceramic sintered material for the components. It is an object of the invention to produce catalytically active components for thermal ionization detectors for gas-chromatographic applications which have long-term thermal, mechanical and chemical stability and have increased sensitivity to the substances to be detected. The optimal parameters of the sintered material which are necessary for the detector should be able to be set in a controlled manner. According to the invention, it is proposed that an oxide-ceramic sintered material which comprises a crystalline phase and an amorphous glass phase be used for the components, with, according to the invention, the amorphous glass phase being formed with from 0.1 to 20% by weight of a caesium compound.
