Welch Materials Xtimate Polar-RP Columns

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.

Xtimate HPLC column derives its outstanding performance from a special hybrid partic le based technique, which coats a unique 5nm organic/inorganic polymer layer on the silica surface, so that the pH range is extended to 1.0-12.5. Xtimate column is designed for HPLC method development. Regardless of the types of mobile phase or high temperature, Xtimate HPLC column always has stable performance and long lifetime.

X features of Xtimate column

eXtra pH range: wide pH range from 1.0 to 12.5, excellent peak shape for strong bases
eXtra column lifetime: 5 times of similar product such as Gemini
eXtra performance: column efficiency of 5μm columns is as high as 90000/m, 2-3 times of that of Xterra
eXtra care from Welch: enjoy excellent pre-sales and after-sales service from Welch
