Ultisil XS-C18 utilizes a unique multilayer bonding process with high bonding density and close ligand spacing, providing excellent spatial shape selectivity. It offers high column efficiency, high column capacity, and high carbon loading, resulting in strong compound retention and exhibiting outstanding steric hindrance selectivity. The column is particularly effective for separating small-molecule isomers, including structural and positional isomers.
Ultisil 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 column is the best choice for method development. owing to complete bonding chemistries and stable performance.
