Formulated to support synthetic operations, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Ec, 3 μm, 110 Å, 4 x 3 mm are designed as pre-columns for High Performance Liquid Chromatography (HPLC). Placed within a guard column holder, they protect the primary HPLC column from contaminants that may cause damage and reduce its lifespan. Featuring medium density monomeric octadecyl (C 18, ODS) modification, these guard columns ensure efficient separation using reversed phase (RP) principle. With a specific surface area of 340 m²/g, they offer excellent adsorption capacity while maintaining pressure stability up to 600 bar and temperature tolerance up to 60°C. Ideal for analytical applications, these guard columns provide reliable performance in
