Designed for professional use, the Pre-column systems for HPLC, specifically the Nucleodur ® Π 2, 5 μm, 4 x 2 mm, are essential components in liquid chromatography (LC, HPLC). These guard columns protect your main HPLC column from contamination by filtering out chemical impurities before they reach the primary column. With a pore size of 110 Å, a pore volume of 0.9 ml/g, and a specific surface area of 340 m²/g, these fully porous particles (FPP) offer excellent separation capabilities. The biphenylpropyl modified surface chemistry ensures optimal performance in acetonitrile-water eluents over a wide pH range of 3.0-10.0. The pressure stability of up to 600 bar makes them suitable for high
