(Top) Evaluation method for vapor phase spectra; shown for the system ethanol/gas mix 2 at T = 373 K and p = 6.5 MPa (calibration spectra recorded in single-phase vapor phase or above the mixtures critical temperature are processed equally); (bottom) correction of liquid film contribution to vapor phase spectrum for the system ethanol/gas mix 2 at T = 373 K and p = 6.5 MPa.
