ABSTRACT:
An electrode system for resistance furnace includes a pair of electrodes, one of which is movable to selectively clamp a resistive crucible between the electrodes. A specimen placed in the crucible is combusted by the application of electrical power to the electrodes in electrical contact with the crucible. One of the electrodes includes a demountable housing extending therefrom for surrounding a crucible held between the electrodes and sealing the crucible between the electrodes. The demountable housing permits easy cleaning of the system by removal of the housing. In one embodiment one of the electrodes includes a surface configurated to engage the crucible and provide self-centering of the crucible as the electrodes are moved to clamp the crucible therebetween.
