Abstract
In an atomic absorption spectrometer, a burner 16 for atomizing a sample is movable between a first and a second position. In the first position, the 'cloud of atoms' is formed in the area of the housing-fixed measuring light beam 14. In the second position, it is formed outside the measuring light beam. The measurement is made in the first position whereby the utilization of the energy of the measuring light beam is optimal. A drift compensation is made in the second position to take care of variations of the lamp intensity and of the detector sensitivity.
