Designed with efficiency in synthetic processes in mind, Macherey-Nagel's Hplc Guard Columns (Analytical) Nucleodur ® C 8 Gravity, 3 μm, 4 x 2 mm are a crucial addition to any lab's chromatography setup. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of up to 400 bar, these guard columns effectively protect your main HPLC column from contamination, extending its lifespan. Featuring fully porous particles (FPP) and a base deactivated (BDS), high density monomeric octyl (C 8 , MOS) modification, they offer excellent separation performance in reversed phase (RP) conditions. Operable within a wide pH range of 1.0 - 1
