TN225 – Silica reactor for gas adsorption

Gas adsorption investigation requires a good contact between the gas and the solid. A silica reactor has been designed for the Calvet DSC111 in which the reactive gas flows through the sample situated on a sintered glass. This particular cell design is especially interesting for the gas-solid reactions or also for the investigation of reactions occurring in a corrosive medium. The exhausted gases are easily analyzed at the outlet of the silica tube by means of a gas chromatograph or a mass spectrometer (see application note AN226).
