Tailored for precision-driven chemical tasks, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Gravity Sb, 3 μm, 4 x 2 mm, offer robust protection for your main HPLC column from contaminants. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of up to 600 bar, these guard columns ensure optimal performance under high-pressure conditions. Featuring fully porous particles (FPP) and a base deactivated (BDS), high-density octadecyl (C 18, ODS) modification, they provide exceptional separation efficiency using acetonitrile-water as eluent. Ideal for reversed-phase (RP) separations, these pre-columns extend the lifespan of your primary
