Ultisil AQ-C18 Column are designed to have extended retention and selectivity for hydrophilic and polar compounds, which are poorly or not at all retained on other phases. Ultisil AQ-C18 avoids so-called “phase collapse” even when 100% water is used. Typical applications are separations of water soluble compounds include biomolecules, metabolites, and pharmaceutical degradants.

Ultisil AQ-C18 columns are designed to have extended retention and selectivity for hydrophilic and polar compounds, which are poorly or not at all retained on other phases. A proprietary bonding chemistry, Ultisil AQ-C18 avoids so-called “phase collapse”, even when 100% water is used, a phenomenon that conventional C18 columns typically exhibit at high water content in the mobile phase. Ultisil AQ-C18 phase is fully end-capped to ensure the best peak shapes of polar and basic compounds and longer lifetime. Typical applications are separations of water soluble compounds that cannot be retained on traditional C18 phase. Examples include biomolecules, metabolites, and pharmaceutical degradants such as organic acids, water-soluble vitamins, oligosaccharides, amino acids, and small piptides and nucleotides.

Features

  • No phase collapse, suitable for high aqueous mobile phase
  • Less retentive than XB-C18 for non-polar compounds
  • Increased retention for polar and water-soluble compounds

When in highly aqueous mobile phase, retention for polar compounds such as organic acids, peptides, nucleosides and water soluble vitamins is strong.
Under the same condition, when compared with other brands in highly aqueous mobile phase, Ultisil AQ-C18 shows excellent resistance to phase collapse.
