Abstract
A temperature-programmed desorbed gas analyzing apparatus including a sample chamberin which a sample S is disposed, an infrared heating furnacefor heating the sample S disposed in the sample chambera measuring chamberin which gas desorbed from the sample S by heating is introduced, a turbo molecular pumpfor reducing the pressure in the measuring chambera mass spectrometerhaving a gas detection portiondisposed in the measuring chamberan intermediate pressure-reduced chamberprovided between the sample chamberand the measuring chambera first orificewhich the intermediate pressure-reduced chamberand the sample chamberintercommunicate with each other, and a second orificethrough which the intermediate pressure-reduced chamberand the measuring chamberintercommunicate with each other, and the desorbed gas occurring in the sample chamberis introduced through the first orificethe intermediate pressure-reduced chamberand the second orificeinto the measuring chamberThe pressure in the intermediate pressure-reduced chamberor the measuring chamberis controlled by pressure adjusting unit so as to be fixed.
