Other, less popular reversed-phase solvents include tetrahydrofuran and acetone. While normal-phase allows the use of a wide range of solvents with different selectivity options, reversed-phase is limited.
WebNormal phase chromatography, an adsorptive mechanism, is used for the analysis of solutes readily soluble in organic solvents, based on their polar differences such as amines, acids, metal complexes, etc.. Reversed-phase chromatography, a partition mechanism, is typically used for separations by non-polar differences.
