ReproSil 300 Polyamin from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 300 Å pore size and a polyamine-bonded phase. This stationary phase provides strong polar interactions and is ideally suited for the separation of carbohydrates, glycoproteins, and other polar biomolecules in HILIC or normal-phase mode. The wide-pore design offers excellent accessibility for large biomolecules, while the polyamine chemistry minimizes irreversible adsorption of sugars and glycoproteins, ensuring sharp peaks and high recovery.
ReproSil 300 Polyamin columns from Dr. Maisch HPLC GmbH deliver wide-pore accessibility and strong polar selectivity – the preferred choice for carbohydrate and glycoprotein chromatography in HPLC.
