HPLC Guard Columns (analytical) NUCLEOSHELL ® RP 18, 2.7 µm, 4 x 2 mm

Crafted to support technical production environments, pre-column systems like the Hplc Guard Columns (Analytical) Nucleoshell ® Rp 18, 2.7 μm, 4 x 2 mm play a crucial role in protecting your main HPLC column from contamination. Featuring a core-shell structure with superficially porous particles (SPP), these guard columns have a specific surface area of 130 m²/g, ensuring efficient filtration. With a pore size of 90 Å and a particle size of 2.7 μm, they provide excellent separation performance while maintaining high pressure stability up to 600 bar. Their reversed phase (RP) design, combined with a high density monomeric octadecyl (C 18 , ODS) modification and base deactivated (BDS) surface chemistry, ensures compatibility
