A reliable solution for controlled synthesis, the Hplc Guard Columns (Analytical) Nucleodur ® NH 2 -Rp, 5 μm, 4 x 2 mm, offers excellent pH stability ranging from 2.0 to 8.0 and temperature resistance up to 60°C. With a specific surface area of 340 m²/g as per BET, these fully porous particles (FPP) provide ample interaction sites for efficient separation. The 4mm long column, featuring a 2mm internal diameter and 5 μm particle size, ensures optimal flow rate while maintaining high resolution. For enhanced versatility, the columns exhibit both reversed phase (RP) and normal phase (NP) separation principles, making them suitable for various analytical applications.
