Engineered to maintain reliability in process-driven workflows, the HPLC Column Nucleodur ® SIOH, 5 μm, 250 mm, 4 mm is designed for normal phase applications. Based on high purity NUCLEODUR ® silica gel, this unmodified phase is suitable for separating polar and midpolar compounds. Featuring a particle size of 5 μm, fully porous particles (FPP), and a pore size of 110 Å, it offers a specific surface area of 340 m²/g and a pore volume of 0.9 ml/g. The column's pressure stability reaches up to 600 bar, while its temperature stability extends to 60°C. With a recommended eluent of n-heptane and a pH stability range of 2.0-
