Recommended for applications requiring controlled solvent behavior, the Hplc Guard Columns (Analytical) Nucleodur ® NH 2 -Rp, 5 μm, 4 x 3 mm offer effective protection against contaminants that may damage the main HPLC column. With a pore size of 110 Å, these fully porous particles (FPP) provide a large surface area of 340 m²/g, ensuring efficient separation while maintaining pressure stability up to 600 bar. The aminopropyl (NH 2 ) surface modification offers multi-mode (RP and NP) and reversed phase (RP) separation principles, making them suitable for a wide range of analytical applications. The columns exhibit temperature stability up to 60 °C and are compatible with acetonitrile-water eluents, offering versatile compatibility for various sample types
