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. WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Simply put, HILIC is a normal-phase type of separation but uses reversed-phase type eluents.
WebHILIC can be described as a variation of reversed phase chromatography performed using a polar stationary phase.
