Optimized for controlled laboratory processes, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Ec, 5 μm, 300 Å, 4 x 2 mm, are designed as pre-columns to protect your main HPLC column from contamination. With a specific surface area of 100 m²/g according to BET, these fully porous particles (FPP) offer a pore volume of 0.9 ml/g and a carbon content of 17.5 %. They are end-capped and feature medium density monomeric octadecyl (C 18 , ODS) modification, ensuring excellent separation performance under reversed phase (RP) conditions. The columns have a pressure stability of up to 450 bar and a temperature stability of 60 °C, making them suitable for various analytical applications. Their
