Optimized for controlled laboratory processes, the Hplc Guard Columns (Analytical) Nucleodur ® Phenyl-Hexyl, 1.8 μm, 4 x 3 mm, are designed as pre-columns to protect your main HPLC column from contamination. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a particle size of 1.8 μm, these fully porous particles (FPP) offer excellent separation performance under reversed phase (RP) conditions. The phenylhexyl modification ensures compatibility with acetonitrile-water eluents while maintaining a pressure stability of up to 800 bar. With a carbon content of 10 %, these guard columns provide robustness and longevity for your analytical HPLC applications.
