ReproSil 200 Diol from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 200 Å pore size and a diol-functionalized bonded phase. This stationary phase provides moderate polarity and hydrogen bonding capability, making it ideal for size exclusion chromatography (SEC) of proteins, glycoproteins, and other biomolecules, as well as for normal-phase and HILIC separations. The wide-pore design ensures efficient mass transfer and optimal accessibility for larger molecules, while the diol surface reduces irreversible adsorption of polar analytes.
ReproSil 200 Diol columns from Dr. Maisch HPLC GmbH deliver versatile wide-pore chromatography – the ideal choice for SEC, normal-phase, and HILIC biomolecule separations.
