用于分光目的样品的电热雾化，特别是用于原子吸收的装置 - 光谱，其包括两个触点（54,56）之间的炉（10）被保持。 触头（54,56）的炉子（10）围绕接合和形成空腔（58），触头（54,56）之间，绝缘间隙（88）形成。 该间隙（88）是通过由陶瓷毡的密封件（142）封闭。 在所述腔（58）发起的保护气体然后只能通过炉（10）和样品导入口（116，120）的孔（14）流出。 由此减少保护气体的消耗。 此外，定义流条件和炉的加热是在（10）在空腔（58）结果扩展保护气体。

An apparatus for electrothermal atomization of a sample for spectroscopic purposes, in particular for atomic absorption - spectroscopy, comprising a furnace (10) between two contacts (54,56) is maintained. The contacts (54,56) engage around the furnace (10) and form a cavity (58), between the contacts (54,56), an insulating gap (88) is formed. This gap (88) is closed by a seal (142) made of ceramic felt. Into the cavity (58) initiated protective gas then flows out only via a bore (14) of the furnace (10) and sample introduction openings (116, 120). There the inert gas consumption is thereby reduced. In addition, defined flow conditions also for itself during the heating of the furnace (10) expanding inert gas in the cavity (58) result.
