Welch Materials Xtimate C18 Columns

Xtimate C18 column utilizes Welch's patented organic-inorganic hybrid surface technology to modify the silica gel matrix. Specifically designed for liquid chromatography method development, it allows the use of a variety of mobile phase systems across a wide pH range and temperature conditions. Even under the most stringent conditions, it offers highly stable performance and a longer lifespan, with a longer service life than regular C18 columns under standard conditions.

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
