Welch Materials Ultisil Plus C18 Columns

Ultisil Plus series features exceptional anti-fouling capability, ensuring outstanding longevity while analyzing complex matrix samples.

Ultisil Plus C18 column has a lower specific surface area, slightly larger pore size, and lower carbon loading, resulting in weaker retention compared to XB-C45. The double end-capping process ensures excellent peak shape when analyzing acidic and basic polar compounds.

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.

Features

Ultra-pure spherical porous silica, purity > 99.999%
Wide pH range: 2.0-8.0
High efficiency: theoretical plate > 80000/m
Excellent peak symmetry: tailing factor=0.95~1.05
Exceptional lot-to-lot reproducibility
