Ultisil AQ-C18

by Welch Materials

Ultisil AQ-C18 columns are designed to show extended retention and selectivity for hydrophilic and polar compounds, which are either not or poorly retained on other phases.

  • No phase collapse; suitable for high aqueous mobile phase
  • Endcapped for excellent peak shape of polar, acidic and basic compounds
  • Less retentive than XB-C18 for non-polar compounds
  • Increased retention for polar and water soluble compounds
  • Excellent for applications for water soluble compounds that typically cannot be retained on traditional C18 phase, including biomolecules, metabolites, pharmaceutical degradants such as organic acids, water-soluble vitamins, oligosaccharides, amino acids, and small peptides and nucleotides.
Application areas:
Acidic compounds Amino acids Basic compounds Bio-molecules Hydrophilic compounds Metabolites Nucleotides Oligosaccharides Organic acids Peptides Pharmaceutical molecules Polar compounds Vitamins
