ABSTRACT:
The present invention is a thermogravimetric instrument having a ceramic sample support and a ceramic balance beam. The ceramic platform is rigidly attached to the hot end of the ceramic balance beam. An inert metal liner is press fitted into the ceramic sample platform. In a preferred embodiment, a thermocouple is directly attached to the inert metal liner. The thermocouple wires are routed through the length of the ceramic balance beam and are attached to the cold end of the ceramic balance beam with adhesive. The inert metal liner could be fabricated from platinum or from platinum alloys.
