Hilic mechanism
Web•HILIC is a variation of normal-phase chromatography •Stationary phase is a polar material such as silica, cyano, amide, etc. •A high organic-low aqueous mobile phase •i.e. water is the elution solvent •Mechanism is a combination of weak cation exchange and partitioning into the adsorbed aqueous layer WebHILIC Stationary Phases. Understanding the possible HILIC retention mechanisms involved for a particular column-solvent-analyte system is crucial in the process of selecting the right HILIC stationary phase leading to a successful application.

WebJun 12, 2014 · The mechanism of HILIC retention is popularly, considered as partitioning of the analyte into the water rich layer, which forms on a polar stationary phase surface. However, this is a popular view. WebEvidence suggests that the retention mechanism in HILIC is complex, and consists of a combination of: Hydrophilic partitioning of the analyte between the aqueous-rich layer …
WebAug 15, 2013 · It is also important to notice that the ion-exchange mechanism, always present with HILIC phases, plays a major role for the retention of peptides. Based on my own experience, I would indicate that 95% of peptides can be adequately analysed in HILIC thanks to the ion-exchange contribution.
