Spectroscopic analysis of composite hydrocarbon mixtures

The experimental researches of relations of an absorption coefficient from concentration in binary hydrocarbon mixtures are executed and is shown, that this relation in different mixtures types can have a different degree of non-linearity. The linear approximating of this relation is possible at concentration of aromatic hydrocarbon approximately up to 30 … 40 %. Is shown, that the presence of this linear part can be used for calculation of components concentrations in composite hydrocarbon mixtures on regressions equations with factors, established by results of experiments only with binary mixtures.
