NUCLEODUR® HILIC is an ammonium – sulfonic acid modified silica phase for HPLC.

• High purity spherical silica gel
• Hydrophilic phase for hydrophilic interaction chromatography (HILIC)
• Separation mechanism based on partition chromatography between the organic/aqueous mobile and the polar stationary phase

The HILIC phase is recommended for hydrophilic compounds such as organic polar acids and bases, polar natural compounds, nucleosides, oligonucleotides, amino acids, peptides, and water soluble vitamins.

EC guard columns are used for analytical EC columns with the Column Protection System guard column holder (554-5851).
