Ultisil TM Series HPLC Columns are based on ultra-pure (purity >99.999%) spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil TM Series column is the best choice for method development, owing to complete bonding chemistries and stable performance.
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. Typical applications are separations of water-soluble compounds that cannot be retained on traditional C18 phase. It could replace Aquasil C18, AtlantisC18, HydroBond AQ-C18, Prontosil C18, YMC ODS-AQ, Agilent(economic) TC-C18(2), Elite Sino Chrom ODS-BP etc.
Key Features
- Compatible with 100% water
- Less retentive than XB-C18 for non-polar compounds
- Increase retention for polar and water-soluble compounds
- Unique bonding chemistry and double end-capping technology
- High efficiency: theoretical plate＞9000/m
- Excellent peak symmetry: tailing factor=0.95-1.05
- Wide pH range: 1.5-10
- Exceptional lot-to-lot reproducibility
Typical Applications
- Separations of water-soluble compounds
- Biomolecules, metabolites, and pharmaceutical degradations such as organic acids, water-soluble vitamins, oligosaccharides, amino acids and small peptides and nucleotides
