ABSTRACT:
A furnace for extracting gaseous components from material samples includes upper and lower electrodes mounted to press therebetween a crucible of electrically conductive material. An electric current is applied to the electrodes, thereby causing heating of the material sample contained in the crucible, with the result that gaseous components are extracted from the material sample. At least one of the upper and lower electrodes is rotated about a vertical axis, thereby causing surfaces of the crucible contacting respective surfaces of the upper and lower electrodes to rotate under friction against such respective surfaces, thereby improving electrical contact between the crucible and the electrodes.
