Welch Materials Xtimate CN Columns

Xtimate CN is made on a silica matrix modified with Welch’s patented organic–inorganic hybrid surface technology. It supports a wide range of mobile phase systems and a broad temperature window for method development in a broad pH range. With selectivity distinct from C18 and C8 reversed-phase columns, Xtimate CN is well suited for strongly hydrophobic compounds, as well as samples that cannot be eluted on conventional reversed-phase columns.

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
