Abstract
The invention relates to catalytically active components for thermal ionization detectors for the detection of compounds containing halogen which have an improved structure as well as to a manufacturing method for an oxide ceramic sintering material for the components. It is the object of the invention to manufacture catalytically active components for thermal ionization detectors for gas chromatographic applications which are thermally, mechanically and chemically stable in the long term and which have increased sensitivity to the materials to be detected. In this respect, the sintering material should be adjustable in a controllable manner in the ideal parameter required for the detector. It is proposed in accordance with the invention to use an oxide ceramic sintering material for the components which comprises a crystalline phase and an amorphous glass phase, with it being essential to the invention that the amorphous glass phase is formed with 0.1 to 20% by weight of a cesium compound.
