摘要： A graphite tube furnace for atomic absorption spectroscopy has a specimen support. The graphite tube furnace is constructed with zones disposed substantially symmetrically around the center of the furnace. The shape of the zones is largely matched and matchable to the functions of the device, such as electric contacting, prevention of heat sinks, restriction of an atomization chamber, provision of an atomization chamber and holding of the specimen support. The specimen support is formed in such a way that in practice it is no longer heated by Joulean heat or thermal conduction, it is secured against movements and it has a minimal mass.
