WebHILIC Overview. 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 ...

WebJan 1, 2024 · HILIC-ESI-FTMS with ammonium acetate was an effective mean for separation and enrichment of oligosaccharides and its alditols for MS analysis and also provide … WebFeb 1, 2024 · HILIC-FTMS analysis was performed on an Agilent 1290 LC UPLC system (Agilent Technologies, Wilmington, DE, USA) equipped with a LTQ ORBITRAP XL mass spectrometer (Thermo, SCIENTIFIC, USA). The FCS hm oligosaccharides were separated by a Luna HILIC column (150 × 2.00 mm, 3 μm, Phenomenex) at 25 °C. WebHILIC or Hydrophilic Interaction Liquid Chromatography is a high-performance liquid chromatographic (HPLC) technique for separation of polar and hydrophilic compounds. Originally the separation technique was called "Hydrophilic-Interaction Chromatography", and occasionally the expression "Aqueous Normal Phase" has also been used. health source 75482
