Prepared for use in regulated laboratory conditions, the Hplc Guard Columns (Analytical) Nucleodur ® C 8 Gravity, 5 μm, 4 x 5 mm are designed as pre-columns to protect your main HPLC column from contamination. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a particle size of 5 μm, these fully porous particles (FPP) offer high efficiency and excellent separation performance. The base deactivated (BDS), high density monomeric octyl (C 8 , MOS) modified surface chemistry ensures optimal compatibility with acetonitrile-water eluents, while maintaining a pressure stability of up to 400 bar and temperature stability of 60 °C. By using these guard columns, you can extend the lifespan of your
