Designed for professional use, the Hplc Guard Columns (Analytical) Nucleodur ® Polartec, 1.8 μm, 4 x 2 mm are pre-column systems designed to protect your main HPLC column from contamination. With a particle size of 1.8 μm and a pore size of 110 Å, these guard columns are ideal for reversed phase separation using acetonitrile-water as eluent. Featuring fully porous particles (FPP), octadecyl phase (C18, ODS) modification with embedded polar group (PEG), and a specific surface area of 340 m²/g according to BET, they offer excellent performance and longevity. The guard columns have a pressure stability of up to 900 bar and a pH stability range of 1.0-9.0,
