WebFeb 9, 2024 · Temperature affects the degree of adsorption of mobile phase components and the solutes on the stationary phase. It also affects the composition of the solvent sheath around solute molecules. These major aspects of SFC are almost completely ignored! Pressure tends to be a secondary control variable in SFC. WebSolvents such as methanol or acetone have an analogous advantage over water. In difficult cases hydration numbers have been estimated at remarkably low temperatures. ... but rather as the average number of molecules resident in a solvent sheath around the polymer during the time scale of the experiment.
