HPLC Columns – HILIC Columns
HILIC: Hydrophilic Interaction Chromatography
Hydrophilic Interaction Chromatography (or Hydrophilic Interaction Liquid Chromatography, HILIC) is a variant of normal phase liquid chromatography that partly overlaps with other chromatographic applications such as ion chromatography and reversed phase liquid chromatography (RP HPLC). HILIC uses hydrophilic stationary phases with reversed-phase type eluents.
Functionalized polyvinyl alcohol gel gives the HILIC columns series a wide usable pH range (2 – 12), excellent chemical stability, and low shedding for sensitive detectors (MS, CAD, ELSD) .
Various Amino Functional groups complete the superior Performance of the Shodex HILIC columns for HILIC separations.
They Simplify HPLC methods by removing ion pair reagents and explore basic mobile phases. Tackle challenging separations with mulitmode capabilities (HILIC + Ion Exchange) and optimization for various Saccharides: Monosaccharides, oligosaccharides, Polysaccharides and other various compounds.

HILIC: Hydrophilic Interaction Liquid Chromatography
- Polymer-based packing material provides excellent chemical stability and minimum deterioration over an extended time period.
Suitable for polar analytes (like in IEX chromatography, IEC and IC)
Polar stationary phase (like in NP chromatography)
Polar mobile phase, e.g. water/ACN mixtures (like in RP chromatography)
HILIC Columns are used mainly for the separations of:
Various Saccharides (food and feed industry)
mono saccharides analysis

HILIC - Chromatography
Professor Alpert introduced a new concept in 1990: hydrophilicity chromatography (HILIC). This chromatographic method is used to separate strong polar and hydrophilic compounds, such as nucleosides and nucleotides, amino acids, sugars, etc. Besides, it uses polar stationary phase, polar mobile phase, and solutions with lower polarity than stationary phase, such as acetonitrile/water, etc. Different from reverse phase chromatography, the greater the polarity of mobile phase, the stronger the elution ability in HILIC chromatography. Nevertheless, it is recommended that aqueous phase proportion should not exceed 40% or not less than 3%.
