Engineered to maintain reliability in process-driven workflows, pre-column systems for HPLC such as the Hplc Guard Columns (Analytical) Nucleodur ® Cn-Rp, 5 μm, 4 x 3 mm, serve as essential components in high-performance liquid chromatography (HPLC). These guard columns, specifically designed with a pore size of 110 Å and a particle size of 5 μm, provide effective protection against contaminants that may harm the primary HPLC column. With a specific surface area of 340 m²/g and a carbon content of 7 %, they offer superior separation capabilities in acetonitrile-water eluents using cyano, nitrile (CN) modifications. Capable of withstanding pressures up to 600 bar and temperatures up to 60°C,
