Engineered for consistent performance, the Hplc Guard Columns (Analytical) Nucleoshell ® Rp 18Plus, 2.7 μm, 4 x 3 mm feature core-shell, superficially porous particles (SPP) with a specific surface area of 130 m²/g. With a pore size of 90 Å and a particle size of 2.7 μm, these guard columns offer excellent separation capabilities while maintaining a pressure stability of up to 600 bar. Their monomeric octadecyl (C 18 , RP 18 , ODS) modification ensures polar selectivity, making them ideal for use with acetonitrile-water eluents. Furthermore, their end-capping and wide pH stability range of 2.0-9.0 ensure long-lasting performance and compatibility with various
