Designed with efficiency in synthetic processes in mind, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Gravity, 3 μm, 4 x 3 mm are pre-column systems designed to protect your main HPLC column from contamination. With a pore size of 110 Å and a specific surface area of 340 m²/g, these guard columns efficiently filter out chemical impurities before they reach the main column, thereby extending its lifespan. Featuring fully porous particles (FPP) and a base deactivated (BDS), high density octadecyl (C 18, ODS) modification, these guard columns offer excellent separation performance under pressures up to 600 bar. Ideal for use with acetonitrile-water eluents, these guard columns ensure optimal results in your analytical work
