Intended for structured formulation workflows, the Pre-column systems for HPLC, specifically the Hplc Guard Columns (Analytical) Nucleodur ® Π 2 , 3 Μm, 4 X 3 Mm, serve as essential protective measures against contaminants that may harm the main HPLC column. With a pore size of 110 Å and a specific surface area of 340 m²/g, these fully porous particles (FPP) provide optimal filtration capabilities. The biphenylpropyl modified surface chemistry ensures compatibility with acetonitrile-water eluents, while the 3 μm particle size and 4 x 3 mm L x Ø internal dimensions offer pressure stability up to 600 bar. By utilizing these guard columns, researchers can extend the lifespan of their main HPLC columns,
