Produced for stability across temperature-sensitive applications, the Hplc Guard Columns (Analytical) Nucleodur ® C 8 Ec, 5 μm, 4 x 2 mm are designed to protect your primary HPLC column from contaminants. With a pore size of 110 Å, these guard columns effectively filter out impurities, extending the lifespan of your main column. Featuring medium density monomeric octyl (C 8 ) modification as the separation principle, they ensure efficient reversed-phase separations in acetonitrile-water eluents. The fully porous particles (FPP), with a particle size of 5 μm and a specific surface area of 340 m²/g, provide excellent pressure stability up to 600 bar and temperature tolerance up to 60°C. By utilizing these guard columns, you
