FIELD: physics, measurement. ^ SUBSTANCE: invention is related to methods for investigation of quantitative-qualitative composition of different mixtures. In method investigated mixture is excited by laser radiation, afterwards spectrum of its Raman scattering is registered. When quantitative content of components is determined, basic value Ij of Raman scattering strip intensity is selected, which corresponds to j component of mixture, where j=1ÇN, and N is total number of mixture components, afterwards ratio of Raman scattering strips intensities is defined for every investigated component of mixture and specified basic value Ik/Ij, where k=1ÇN, këáj. Afterwards ratio of every component concentration is calculated to concentration of basic j component, and then partial concentration pl is calculated for every component. ^ EFFECT: provision of partial concentrations of mixture components with specified extent of accuracy and possibility to control mixture samples directly in reservoirs installed at arbitrary distance from metering equipment both in zone of sight line and outside, using simple equipment. ^ 4 cl, 1 dwg |
