| Abstract: | Methods providing control of the selectivity of a coupled column were compared. The method of vacuum barochromatography has been developed. This method allows the selectivity of a coupled column to be controlled over a broad range of the Rohrschneider scale using medium carrier-gas pressures. The possibility of identifying the components of a complex mixture based on chromatographic spectra was considered.Translated fromIzvestiya Akademii Nauk.
