Ultisil AQ-C18
– 82 columns
Vendor: 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.
