Solvent affinity
WebJul 18, 2024 · This difference is due to the relative affinities of analytes with stationary and mobile solvents. The more the relative affinity with a stationary phase an analyte has, the more it will stay in place, and the lesser the Rf value will get and vice versa. Rf value is the characteristic identification value for analytes at given temperatures. WebAug 12, 2024 · To further a most properly solvent choice, or its components in the case of the DES, in silico tools, such as the COSMO-based models (conductor-like screening model), have been successfully applying. These theoretical models are able to describe the solute–solvent affinity considering the charges in the molecule configuration [14,15,16].
