Popis: Methods for evaluating concentrations in analysis with the use of an EMAL-2 laser energy–mass analyzer are described. Analytical signals are calculated using the integrated intensity of spectral lines. The characteristic curve of a photographic emulsion is approximated by the function \(F(x) = \int_{ - \infty }^a {e^{ - x^2 } } dx\). The possibility of taking into account doubly and triply charged ions in the evaluation of concentrations is analyzed. It is shown that taking into account multiply charged ions reduces the relative root-mean-square deviation from 0.18 to 0.03.
