Welch Materials Xtimate C4 Columns

Xtimate C4 column uses modified silica from the Xtimate series, retaining the advantages of the series. It is the preferred choice for MS and ELSD detectors.

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
