WebMar 1, 2024 · HILIC offers a wide variety of different retention mechanisms and column selectivities. Stationary phases can be classified in neutral ligand (e.g. amide), charged (e.g. unbonded silica) and zwitterionic phases (e.g. sulfobetaine) based on the characteristics of the functional group. WebIn HILIC mode, the aqueous mobile phase is the strong (or eluting) solvent versus the more familiar reversed-phase mode, where elution is the result of the organic solvent strength. Column Conditioning and Re-Equilibration are Essential for Retention Time Reproducibility
