Developed for demanding processing applications, the Hplc Guard Columns (Analytical) Nucleodur ® PFP, 1.8 μm, 4 x 3 mm are designed to protect your primary HPLC column from contamination. With a particle size of 1.8 μm and a pore size of 110 Å, these guard columns offer excellent separation performance using reversed phase (RP) as the separation principle. Featuring fully porous particles (FPP), they have a specific surface area of 340 m²/g, ensuring optimal interaction with various analytes. Additionally, their surface chemistry is modified with pentafluorophenylpropyl (PFP), making them suitable for eluents such as acetonitrile-water mixtures. These guard columns are endcapped, ensuring stable column efficiency even under high pressure conditions up to 80
