Silica Hydride HPLC Columns Unbonded
The Cogent Silica-C™ is HPLC grade silica with a silicon hydride surface (silica hydride). Made completely free of carbon, this unique stationary phase
will adsorb and desorb solvents commonly used in mobile phases very differently from ordinary silica resulting in fantastic benefits to the chromatographer.

Totally Inorganic | Will Not Adsorb Water | Use for Prep or Analytical |
Since these columns have virtually no silanols remaining (less than 2%), they do not have a strong association
with water and other solvents and will not have the expected hydration shell of other silica based columns. This allows you to use them for normal phase HPLC without having to
concern yourself with the moisture content of the solvents.
Excellent choice for normal phase and preparative chromatography because they produce a very unique selectivity are extremely stable for long column life and can be used to retain some polar compounds making it a favorite of many doing LCMS and medicinal chemistry.
