HPLC Guard Columns (analytical) NUCLEODUR ® C 18 HTec, 1.8 µm, 4 x 3 mm

Suitable for laboratory and industrial environments, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Htec provide essential protection for your primary HPLC column against contamination. With a particle size of 1.8 μm and a length of 4 mm, these guard columns are designed to prevent chemical impurities from reaching the main column, thereby extending its lifespan. Featuring a base deactivated (BDS), high density octadecyl (C 18, ODS) modification, these fully porous particles (FPP) offer a specific surface area of 340 m²/g and a pore size of 110 Å. The guard columns are stable within a pH range of 1.0-11.0 and can withstand pressures up to 800 bar. Ideal for reversed phase (
