Claims (5)
- 真空容器内において高温の試料を計量皿に載置してその質量変化を測定可能な真空質量測定装置であって、前記真空容器の下部に前記真空容器と気密に隔絶した熱遮蔽箱を設け、該熱遮断箱に秤量手段を内蔵し、該秤量手段は前記真空容器中に配置した前記計量皿を荷重伝達棒を介して支持し、前記計量皿を前記秤量手段から遠隔的に分離して前記秤量手段に前記計量皿の負荷が伝達しないようにする分離手段を設け、前記真空容器内を真空とした測定状態において前記計量皿を前記秤量手段から分離し前記秤量手段の零点調整を行うことを特徴とする真空質量測定装置。
- 前記真空容器の上部に、前記試料を前記計量皿に載置するための開閉可能な蓋部を設けた請求項1に記載の真空質量測定装置。
- 前記分離手段は前記荷重伝達棒を2つの部材から構成し、両部材を上下に分離するようにした請求項1又は2に記載の真空質量測定装置。
- 前記荷重伝達棒の前記計量皿を固定した上部を、機械的手段により持ち上げ前記秤量手段から分離するようにした請求項3に記載の真空質量測定装置。
- 前記熱遮蔽箱は前記真空容器と磁性流体により気密に隔絶した請求項1〜4の何れか1つの請求項に記載の真空質量測定装置。
