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

Designed for professional use in pre-column systems for HPLC, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Isis offer superior protection for your main HPLC column from contamination. With a particle size of 3 μm and a pore size of 110 Å, these fully porous particles (FPP) provide a specific surface area of 340 m²/g, ensuring optimal separation efficiency. The nonpolar crosslinked polymeric octadecyl (C 18 , ODS) modification offers high steric selectivity, making them ideal for reversed phase (RP) separations using acetonitrile-water as eluent. Featuring a pressure stability of up to 600 bar, these guard columns are designed to handle demanding analytical applications while maintaining their structural integrity.
