HILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase. The mobile phase employed is highly organic in nature (> 60-70% solvent, typically acetonitrile) containing a small percentage of aqueous solvent/buffer or other polar solvent. The water in the mobile phase forms an ...
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 WebHydrophilic interaction chromatography (HILIC) is a valuable alternative to RP-HPLC separations of polar compounds. It is based on the partitioning of the analytes between a highly organic mobile phase (mostly acetonitrile) and a water layer formed at the surface of polar stationary phase.
WebSep 30, 2004 · The retention of 100 peptides was studied during HILIC on amide column using an acetonitrile–water mobile phase containing 0.2% trifluoroacetic acid+0.2% triethylamine as the mobile phase in a linear gradient elution system. The retention times of 100 peptides on amide column are listed in Table 4. The peptides were used without …
WebHydrophilic interaction liquid chromatography (HILIC) is a chromatographic technique used to improve the retention of strong polar substances in reversed-phase chromatography. It works by adopting a strong polar stationary phase and combining the mobile phase with a high proportion of organic phases. pinemeadow eleWebLabeled N-glycans were analyzed by amide hydrophilic interaction chromatography with fluorescence detection (HILIC-HPLC-FLD) (Figure 5).
