材料研究における TPD-MS (Temperature Programmed Desorption or Decomposition Mass-Spectrometry) の応用

概要

論文の詳細を見る
In the material research, TG-MS, pyrolysis-GC are often used in order to obtain the thermal properties of the materials such as gas evolution. On the other hand, TPD (Temperature Programmed Desorption) technique was used for the solid acid-base characterization in the catalysis research. We designed new TPD-MS (Temperature Programmed Desorption or Decomposition Mass-Spectrometry) instrument for comprehensive use. Some applications taken by TPD-MS were shown in the following characteristics. 1) evolved gas analysis which has more than one order of magnitude higher sensitivity than TG-MS, 2) analysis of chemical adsorption and desorption properties, 3) thermal decomposition analysis of air sensitive materials.
