Developed to align with modern chemical standards, pre-column systems like the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Pyramid, 3 μm, 4 x 2 mm play a crucial role in protecting your main HPLC column from contamination. Featuring a pore size of 110 Å, a specific surface area of 340 m²/g, and a particle size of 3 μm, these fully porous particles (FPP) offer excellent pressure stability up to 600 bar. With a carbon content of 14 %, they are designed for optimal performance when used with acetonitrile-water eluents. Their octadecyl (C 18, ODS) modification and polar endcapping ensure reliable separation principles based on reversed phase (RP). To further extend the lifespan of
