Manufactured to meet research and production requirements, the HPLC Guard Columns (Analytical) Nucleodur ® Polartec, 5 μm, 4 x 3 mm, are designed as pre-columns to protect your main HPLC column from contamination. With a particle size of 5 μm and a pore size of 110 Å, these fully porous particles (FPP) offer a specific surface area of 340 m²/g, ensuring efficient filtration. The reversed phase (RP) separation principle, combined with an octadecyl phase (C18, ODS) modification featuring an embedded polar group (PEG), ensures optimal performance under acetonitrile-water eluent conditions. These guard columns boast pressure stability up to 600 bar, making them suitable for various analytical applications while maintaining a compact footprint with a length of
