Variables in Spectrochemistry and Spectral-Line Intensity

  • P. W. J. M. Boumans


In spectrochemical analysis, emission spectra of atoms and ions (and sometimes of molecules) are used for detecting and determining chemical elements. To ascertain the concentrations of the elements in the samples, ‘intensities’ of spectral lines are evaluated. The basis of quantitative spectrochemical analysis is a simple, empirical relationship between the content G of an element in the sample and the intensity I of a spectral line in the source of excitation. This relationship is usually expressed by the Scheibe—Lomakin equation
$$I=K\times {{G}^{m}}$$
or by an equivalent expression.
