Advantages of HILIC | Thermo Fisher Scientific

Achieve better separation efficiency under highly aqueous conditions

Retention of hydrophilic compounds that are difficult to retain by Reversed Phase Liquid Chromatography (RPLC)
Improved sensitivity with MS detection (due to more efficient desolvation of the analytes)
Compatibility with SPE extracts which are often in 100% organic solvent
Low back pressures due to the low viscosity of the organic-rich mobile phases
Separation efficiency of very polar analytes in HILIC better than in RPLC under highly aqueous mobile phase
