Abstract
Use of binary modifiers in supercritical fluid chromatography (SFC) enhances the solvating capabilities of the supercritical mobile phase, allowing the mobile phase to be chemically tailored to a specific separation. The effects of temperature, density and modifier mole fraction on the retention process in capillary SFC was studied. Selectivity, as well as the enthalpy of solute transfer, were seen to be dependent on modifier concentration. Specific molecular interactions between the binary fluid and the solutes as well as enhanced solvation of the bonded stationary phase are suggested by the experimental data.
期刊介绍：
The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
