Übersetzung im Kontext von „ BET method “ in Englisch-Deutsch von Reverso Context: The adsorbent according to claim 1 or 2, wherein the specific surface area. Die BET -Messung ist ein Begriff für ein Analyseverfahren zur Größenbestimmung von Oberflächen, insbesondere poröser Festkörper, mittels Gasadsorption. Streng genommen handelt es sich nicht um eine Messung, sondern vielmehr um eine Methode der Oberflächenchemie. If the principle of operation of the instrument requires the determination of the dead volume in the sample tube, for example, by the admission of a non-adsorbed gas, such as helium, this procedure is carried out at this point, followed by evacuation of the sample. The theoretical background of the adsorption isotherm equation of Brunauer, Emmett and Teller is reviewed, together with the experimental techniques available for measuring physical adsorption of gases by solids. Type of analysis XRD, Laser Diffraction etc. This will be sample dependent, see [8] for more details. If you spot any errors or admissions, or have any comments, please let me know. The samples are dried with nitrogen purging or in a vacuum applying elevated temperatures.
