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

Adapted for use across diverse chemical handling environments, the HPLC Guard Columns (Analytical) Nucleodur® C 18 Gravity, 3 μm, 4 x 3 mm offer enhanced protection for primary HPLC columns against contaminants. With a pore size of 110 Å, these short columns effectively filter out impurities before they reach the main column, extending its lifespan. Featuring fully porous particles (FPP), a bifunctional RP phase, and a balanced ratio of propylphenyl and C 18 ligands, these guard columns provide reliable separation performance under pressures up to 600 bar. Ideal for reversed-phase (RP) applications, these guard columns are suitable for acetonitrile-water eluents and exhibit a specific surface area of 340 m²/g as per BET
