Abstract

In an apparatus for electrothermal atomization, which can be used for flameless atomic absorption spectroscopy as well as for flameless atomic emission spectroscopy, a platform positioned in a graphite tube is divided into two functional axially adjacent. One of the regions serves as the holding part and the other serves as the sample-carrying part. The holding part is mounted in the area of one of the tube ends and the sample-carrying part protrudes unsupported into the interior of the tube.
