Engineered for consistent performance, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Htec, 3 μm, 4 x 2 mm are designed to protect your main HPLC column from contamination. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a particle size of 3 μm, these fully porous particles (FPP) offer high efficiency and reproducibility. The base deactivated (BDS), high density octadecyl (C 18 , ODS) modified surface chemistry ensures optimal separation principles through reversed phase (RP). The columns' pressure stability up to 600 bar guarantees reliable operation under various conditions. For maximum compatibility, they are suitable for acetonitrile-water eluents and have a pH stability range of
