WebNov 1, 2012 · HILIC mode, with high level of organic solvent, possessed good resolution for polar compounds. According to results above, this WCX column could be employed in HILIC mode owing to its polar stationary phase. Improved resolution and peak shape were obtained in the HILIC mode compared with the result in WCX mode ( Fig. 6 ). Webessentially resemble well the results by Alpert, indicating that the mechanism proposed in HILIC can be applied with metal reduction in organic solvents using Nylon 6,6 and ion exchange filters.

Web“HILIC” stands for Hydrophilic Interaction Liquid Chromatography. It is a separation mode that uses a polar stationary phase, which can be bare silica, like the Raptor HILIC-Si … WebHILIC Retention Mechanism HILIC is often presented as a variation of normal-phase liquid chromatography (NPLC), because both methods are based on the use of polar stationary phases and the retention increases with the increase of analyte polarity ( 3, 7, 19 ).
WebHILIC retention mechanism is more complex in comparison to other chromatographic separation modes and many scientists are still striving to understand it fully. It is often described as a mixed-mode mechanism, where several kinds of interaction contribute simultaneously to the overall retention. WebHILIC or hydrophilic interaction liquid chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. …
