HILIC Columns and Accessories - YMC-Triart Diol-HILIC
High-Performance Columns for Polar Compound Separations
Hydrophilic Interaction Liquid Chromatography (HILIC) is a powerful separation mode specifically designed for polar organic compounds that show poor retention in reversed-phase systems.
In conventional reversed-phase HPLC, highly polar compounds often elute near the solvent front or co-elute with matrix components, resulting in poor resolution and ion suppression during MS detection.
HILIC solves this challenge by using a polar stationary phase and a mobile phase rich in organic solvent (typically acetonitrile). A thin, water-enriched layer forms on the silica surface, promoting partitioning and hydrogen-bond interactions that enhance the retention and selectivity of polar analytes.
YMC’s HILIC columns provide exceptional reproducibility, mechanical stability, and compatibility with LC-MS, UHPLC, and high-throughput workflows, which make them ideal for pharmaceuticals, metabolites, and bioanalytical compounds.

When to Use HILIC Chromatography
HILIC is ideal when:
- You need to retain and resolve highly polar compounds not amenable to reversed-phase chromatography
- Polar analytes co-elute near the void in RP-HPLC or suffer from ion suppression
- Your application involves polar pharmaceuticals, metabolites, amino acids, carbohydrates, or nucleosides
- You require MS-compatible separations with high organic content for improved ionization efficiency

HILIC Chromatography FAQs
Q: What is the main advantage of HILIC over reversed-phase chromatography?
HILIC provides superior retention for highly polar compounds that elute too early or not at all in reversed-phase systems.
Q: What mobile phase composition is typically used in HILIC?
Common mobile phases contain 60–95% acetonitrile with a small proportion of aqueous buffer to establish the water-rich stationary-phase layer needed for polar retention.
Q: Are YMC HILIC columns compatible with LC-MS?
Yes. YMC HILIC columns are fully MS-compatible, offering low bleed, high reproducibility, and enhanced ionization efficiency.
Q: What particle sizes and formats are available?
YMC HILIC columns are available in sub-2 µm (UHPLC) and 3–5 µm (HPLC) particle sizes for analytical and high-throughput workflows. Preparative formats are available upon request.
