Built to deliver predictable results in synthesis routines, the Hplc Guard Columns (Analytical) Nucleodur ® Cn-Rp, 3 μm, 4 x 3 mm offer reliable protection against contaminants for your main HPLC column. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of up to 600 bar, these guard columns ensure optimal performance and longevity of your main column. Designed for use with acetonitrile-water eluents, they feature cyano, nitrile (CN) modification and a carbon content of 7%, making them suitable for multi-mode (NP and RP) and normal phase (NP) separations. Operating within a temperature range of 60°C and featuring fully porous particles (FPP) with
