Direct Price Xtimate Polar Rp, 5μm, 4.6×200mm [limited Qty] [5CXF7Wh6]

The Xtimate series columns are specifically designed for liquid chromatography methods, offering the flexibility to use a wide range of mobile phase systems and a broad temperature spectrum across the entire pH range for method development. These columns are based on ultrapure fully porous spherical silica, and feature Welch Materials' unique organic-inorganic graft bonding technology. This technology maintains the high strength and high-resolution core of the silica matrix, while also grafting a highly pH-stable organic hybrid layer on the surface, extending the pH stability range to 1-12.5.

Xtimate Polar RP column is a reversed-phase column with selectivity distinct from conventional C18. It incorporates polar-embedded 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.
