WebFor isocratic HILIC methods, at least 50 column volumes should be used and, for gradient HILIC methods, at least 10 blank injections running the full-time program should be … WebHILIC is one of the most successful approaches for the retention and separation of polar compounds. There are many stationary phases that can be used in HILIC mode, and many phases are generically described as HILIC independently of their chemistry. There is also a variety of misinformation regarding the use of this technique.
WebThe HILIC partitioning process causing chromatographic retention. Present HILIC theory dictates that HILIC retention is caused by a partitioning of the injected analyte solute molecules between the mobile phase eluent and a water-enriched layer in the hydrophilic HILIC stationary phase.

WebThe ACE HILIC MDK provides 3 HILIC column chemistries for polar retention specifically designed to provide alternative selectivity to each other in HILIC mode. The chemistries include: When to use HILIC? The 3 ACE HILIC phases have been shown to provide different elution orders and interactions with a wide range of polar acidic, polar basic and ...
WebHILIC is a particularly useful separation mode for polar organic compounds that are poorly retained by reversed phase. Retention of these polar compounds using reversed phase methods is often difficult because of co-elutions with the solvent front or elutions within the chromatographic region where ion suppression is the greatest. ct 港WebSECTION 3 – CONSIDERATIONS IN METHOD DEVELOPMENT 3.1. HILIC Mode vs. Reversed-Phase Mode The selection of separation mode depends on the type of the analyte molecules and requirement of the specific application. In general, if a highly polar molecule is the analyte of interest, HILIC mode (high organic in the mobile phase) should be considered. ct 濃染WebThermo Fisher Scientific ct 濃淡WebHILIC as well as HPLC, Hydrophilic Interaction Chromatography serves as a practical guide for ...
