Built to deliver predictable results in synthesis routines, pre-column systems for HPLC such as the Hplc Guard Columns (Analytical) Nucleoshell ® Bluebird RP 18, 4 x 2 mm, play a crucial role in maintaining the integrity of your main HPLC column. Featuring a 2 mm inner diameter and 4 mm length, these guard columns are designed with core-shell, superficially porous particles (SPP), providing a specific surface area of 130 m²/g according to BET. With a particle size of 2.7 µm and pore size of 90 Å, they offer excellent separation principles based on reversed phase (RP). Their monomeric octadecyl (C 18 , RP 18 , ODS) modification and polar endcapping ensure high efficiency and reproducibility
