摘要 |
A device for electrothermal atomization of a sample for spectroscopic purposes comprises a furnace (10) which is held between two contacts (54, 56). The contacts (54, 56) surround the furnace (10 ) and form a cavity (58) with an insulating gap (88) being formed between the contacts (54, 56). This gap (88) is closed by a seal (142) made of ceramic felt so that inert gas passed into the cavity (58) emerges only through a bore (14) of the furnace (10) and sample inlet ports (116, 120). Thereby, the inert gas consumption is reduced well-defined flow conditions also result for the inert gas in the cavity (58) which expands when the furnace (10) is heated.
