Abstract
The present invention refers to a method for atomic absorption spectroscopy of an analyte which is contained in a sample to be analyzed and which is converted into free atoms in an absorption volume of an atomizer, said method comprising the steps of (a) position- and time-dependent measuring of the atomic absorption over the cross-section of the absorption volume and (b) simultaneous determination of surface temperatures of the atomizer. This method is characterized by the steps of (c) reconstructing the temperature field in said absorption volume on the basis of the surface temperatures determined, (d) determining position- and time-dependent numbers of particles of the absorbing atoms of the analyte on the basis of the measurements of the position- and time-dependent atomic absorption and the absorption profile that has been determined with due regard to effects influencing the line profile of the analyte and with due regard to the reconstructed temperature field, and (e) determining the time-dependent total number of the absorbing atoms of the analyte on the basis of the position- and time-dependent numbers of particles. In addition, the present invention concerns a device for carrying out this method.
