Built to deliver predictable results in synthesis routines, pre-column systems for HPLC such as the Hplc Guard Columns (Analytical) Nucleodur ® Cn-Rp, 3 μm, 4 x 2 mm, play a crucial role in protecting 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 3 μm, these fully porous particles (FPP) offer excellent separation capabilities while maintaining pressure stability up to 600 bar. Designed for normal phase (NP) separations, these guard columns feature cyano, nitrile (CN) modifications and exhibit temperature stability up to 60°C. By using these guard columns, you can extend the lifespan of your main column and ensure consistent, reliable results in
