Popis: A most significant source of imperfection in emission spectrography is the limited applicability of photographic transformation functions in the region of the emulsion characteristic below the point of inflection. As an alternative approach the use of simple parametric equations, which not only give a “best fit” to the experimental data but also require only few mathematical operations, was investigated.
