Built to deliver predictable results in synthesis routines, the Hplc Guard Columns (Analytical) Nucleoshell ® Bluebird RP 18, available in a pack of four with a dimension of 4 x 3 mm, feature a specific surface area of 130 m²/g as per BET. These pre-columns are designed with core-shell, superficially porous particles (SPP), ensuring a particle size of 2.7 µm and pore size of 90 Å. With a pressure stability of up to 600 bar, they offer excellent performance under high-pressure conditions while maintaining their structural integrity. Their monomeric octadecyl (C18, RP18, ODS) modification ensures compatibility with acetonitrile-water eluents, making them suitable for reversed-phase separations. Additionally, their polar end
