Abstract
A graphite tube furnace with a specimen support for use in atomic absorption spectroscopy has preferably knife-edged shaped flanges on the inner wall surface of the tube furnace. The specimen support is held on the flanges at a distance from the inner wall surface. This avoids the production of heat in the specimen support and heat flow from the tube furnace to the specimen support.
