Luna HILIC HPLC Columns
Luna HILIC HPLC column has a diol phase that provides separation for polar compounds under HILIC conditions
Luna HILIC HPLC Columns

The Luna® brand of columns and media is more than just a product line from Phenomenex. It is a pledge to provide you with the highest level of satisfaction for your chromatographic goals. The Luna HILIC is a diol based silica phase that allows for an denser aqueous layer for increase polar selectivity.

  • Reproducible‚ robust HILIC separations
  • Made for retention of polar compounds
  • Increase mass spectrometry sensitivity

Recommended Use
Diol phase useful for hydrophilic interaction chromatography mode
Long Column Lifetimes and Excellent Performance
Ultra-pure, metal-free silica (99.99 (= 99.99 %) purity) is the backbone of all Luna material. The resulting high quality particles have a surface smoothness, pore structure, and pore consistency to ensure a more uniform particle shape and greater reproducibility.

Increase MS Sensitivity and Retention for Polar Compounds

Hydrophilic Interaction Liquid Chromatography (HILIC) is a separation mode where the partitioning of polar solutes from the high concentration‚ water-miscible‚ organic mobile phase into the hydrophilic surface environment creates separations. Polar solutes exhibit increased retention and elute in the order of increasing hydrophilicity.
