CT-Sil Diol is a diol-functionalized HPLC column based on fully porous, high-purity silica, designed for normal-phase and HILIC (hydrophilic interaction liquid chromatography) applications. The diol groups provide moderate polarity and enable hydrogen bonding and dipole-dipole interactions, offering a less active alternative to bare silica with improved reproducibility and milder retention behavior.
This phase is particularly useful for separating polar compounds, sugars, and isomers, and is compatible with non-polar as well as aqueous-organic mobile phases.
CT-Sil Diol offers controlled polar retention and broad compatibility – a dependable choice for laboratories working with polar analytes in normal-phase or HILIC mode.
