Welch Materials Ultisil Polar-RP Columns

Ultisil Polar RP is a reversed-phase column with selectivity distinct from conventional C18. It incorporates embedded polar groups, allowing the alkyl phase to remain solvated even in highly aqueous mobile phases (up to 100% water) without hydrophobic collapse. It offers enhanced retention and selectivity for 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
