Atomic absorption spectrometer

Atomic absorption spectrometer comprising

• (a) an atomizing device for atomizing a sample which is to be analyzed such that the atoms of the element contained in the sample are present in atomic state in an atomization area,
• (b) a line emitting light source
• (c) an optical system for generating a measuring light beam originating from a line emitting light source and passing through the atomization area,
• (d) and a photo-electrical detector to which the measuring light beam is passed by the optical system after passing through the atomization area, wherein
• (e) the light source, the optical system and the photo-electrical detector (38) are arranged in a housing which forms a sample cavity accessible from outside, which is passed through by a measuring light beam and which is arranged for different atomizing devices optionally being inserted,
• characterized in that
• (f) atomizing devices are assembled to distinct insert units in which the atomizing devices have well-defined positions relative to the insert unit which in turn are arranged to be singly inserted into the sample cavity in a well-defined position to provide an entirely functioning atomic absorption spectrometer.
