[Preparation of multi-hydroxyl molecular-bonded stationary phase for hydrophilic interaction chromatography and its separation property].

The surface of silica was modified by delta-gluconolactone, a multi-hydroxyl molecule, to prepare a new stationary phase for hydrophilic interaction chromatography (HILIC) of strongly polar compounds from traditional Chinese medicine. The separation properties and separation mechanisms of the stationary phase to six polar components were investigated by… CONTINUE READING
