Furnace for the hot extraction of gases contained in solid samples

摘要

The invention relates to a furnace for the hot extraction of gases contained in a solid sample. So that an indirectly heated ceramic crucible and a directly heated graphite crucible 9' can be used alternately in the same furnace without relatively large modifications, the upper electrode 2 has between it and a lower electrode 3' a tubular resistance heating element 4 axially clampable, a collar 11 which is radially directed inwards, reaches over the alignment of the opening 7 in the lower electrode 3 and serves as abutment for the upper edge of a graphite crucible 9'. A stamp (plunger), in conjunction with which the graphite crucible 9' is pressed against the abutment 11, forms the other electrode. <IMAGE>
