Abstract
The method is used in the analysis with polychromatic spectrometers. This method provides determination of high concentrations of chemical elements based on their resonant spectral lines. The intensity measurement is performed at a specific point relative to the centre of the spectral line on the profile of the resonant spectral line. The distance from the centre of the line is selected so that two samples having different concentrations will show the largest possible difference in the measured intensity, and higher intensities shall correspond to larger concentrations of the element.
