Solvent affinity theory
WebThe theory There are several different types of chromatography currently in use – ie paper chromatography; thin layer chromatography (TLC); gas chromatography (GC); liquid ... The solvent that is put into a column is called the eluent, and the liquid that flows out of the end of the column is called the eluate. By a IUPAC definition, solvation is an interaction of a solute with the solvent, which leads to stabilization of the solute species in the solution. In the solvated state, an ion or molecule in a solution is surrounded or complexed by solvent molecules. Solvated species can often be described by coordination number, and the complex stability constants. The concept of the solvation interaction can also be applied to an insoluble material, for example, solvation of functi…
