HILIC columns for separation of polar compounds. Hydrophilic interaction chromatography (HILIC) columns separate polar to highly polar compounds that would be poorly retained in traditional reversed-phase liquid chromatography (LC) separations. Modern, highly orthogonal HILIC phases with short equilibration times and the highest efficiency help ... Web3. What are the common issues in HILIC method development that need to be addressed? analysis of basic compounds, in These are the types of question that HILIC users face and will be addressed within this poster. broadening FIGURE 2.

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 ... list of national capital cities
