Intended for structured formulation workflows, the Hplc Guard Columns (Analytical) Nucleodur ® PFP, 3 μm, 4 x 3 mm, provide essential protection for your main HPLC column from contaminants. 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 primary column. Featuring fully porous particles (FPP), a carbon content of 8 %, and a surface chemistry of pentafluorophenylpropyl (PFP) modification, they are compatible with acetonitrile-water eluents and exhibit a broad pH stability range of 1.0-9.0. Available as short columns with a length of 4 mm and an
