| Popis: | Raman spectroscopy is a unique tool for fast analysis of multicomponent gas media. In this work, we studied the features of application of this method for monitoring the syngas (mixture of CO + H2 + CH4 + CO2 + N2) composition. To determine concentrations, we used contour fit method, where the Raman spectrum of mixture is compared with a synthetically calculated spectrum. The effects of pressure changes and various exposure times on the accuracy of measurements are investigated. It was found that effect of pressure and environment on band contours results in measurement errors several times higher than the errors caused by deviations of the signal intensities. |
