Investigation of atomic vapor absorption spectra on the high-resolution spectrometer "Grand-2000"

Abstract

The work is devoted to the study of atomic vapor absorption spectra obtained in the electrothermal atomizer (graphite furnace) and registered by the high-resolution spectrometer "Grand-2000" (spectral resolution 4 pm). Comparison of the obtained spectra with the spectra recorded by the "Grand-2" spectrometer, which is a part of the "Grand-AAS" atomic absorption spectrometer, indicated the presence of unresolved spectral interferences in the latter, as well as a number of unresolved doublets of analytical lines, both already presented in the database of spectral absorption lines of chemical elements, and missing in it. Based on the results of the work, we can talk about the suitability of the "Grand-2000" spectrometer for adjusting this database.
