Formulated to support synthetic operations, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Htec, 5 μm, 4 x 2 mm, are designed as pre-columns for HPLC systems. With a specific surface area of 340 m²/g and a pore size of 110 Å, these columns effectively protect the main HPLC column from contaminants. Featuring fully porous particles (FPP) and a carbon content of 18%, they offer high pressure stability up to 600 bar. The reversed phase (RP) separation principle ensures efficient filtration, while their base deactivated (BDS), high density octadecyl (C 18, ODS) modification guarantees optimal performance under a wide pH range of 1.0-11.0.
