  • Graphite tube furnace
    Patent number: 5249028
    Abstract: A graphite tube furnace for the electrothermal atomization of specimens for atomic absorption spectroscopy is proposed, which consists of an outer furnace body and an internal inner body. In order to avoid a premature atomization of the specimen, the inner body is designed as a cylindrical tube which is concentrically disposed in the furnace body and which is integrally connected to the furnace body via a single upper, end-face connecting web.
