Intended for structured formulation workflows, the Hplc Guard Columns (Analytical) Nucleodur ® Π 2, 3 μm, 4 x 2 mm are designed as pre-columns to protect your main HPLC column from contaminants. With a pore size of 110 Å, these fully porous particles (FPP) offer a specific surface area of 340 m²/g, ensuring efficient filtration. Featuring a biphenylpropyl modification surface chemistry and a carbon content of 17 %, they provide excellent separation performance using acetonitrile-water eluents. The guard columns have a pressure stability of up to 600 bar and are compatible with a wide pH range of 3.0-10.0. Their compact dimensions, at 4 x 2 mm, make them suitable for various
