Abstract In this paper, we propose new approach to accurate calculation of the molar attenuation coefficient e and the threshold concentration C ∇ , exceeding of which it results in a deviation from Beer's law. The method is based on the asymptotic approximation of the equality of integrals associated with the true values of C ∇ and e as well as their approximate values C i and e i within max. rapprochement: Δ C = min C i - C ∇ and Δ e = min e - e i when C i → C ∇ and e i → e . After reaching the acceptable accuracy, the infinite iterative cycle is interrupted that allows to significantly saving the computing resources.
