ABSTRACT:
In a method for introducing a sample into a graphite tube in flameless atomic absorption spectroscopy a lamella- or crucible-like sample carrier is introduced into the graphite tube from the end face in axial direction. Drying and ashing of the sample is effected outside the graphite tube. The sample carrier may be heated indirectly by radiation or directly by electric current being passed therethrough.
