GromSil 200 Diol is a polar HPLC column from Dr. Maisch HPLC GmbH, based on high-purity, fully porous silica with a 200 Å pore size and bonded with diol (–CH₂OH–CH₂OH) functional groups. The wide-pore structure enables efficient mass transfer and analyte accessibility, making it suitable for separating larger polar compounds such as glycopeptides, oligosaccharides, and hydrophilic biomolecules.
This phase is designed for normal-phase and HILIC-like applications, offering strong dipole and hydrogen-bonding interactions with low surface activity for improved peak shape.
With its broad pore structure and polar selectivity, GromSil 200 Diol from Dr. Maisch HPLC GmbH is ideal for laboratories seeking robust normal-phase or HILIC-style separations of large or hydrophilic compounds.
