HPLC Guard Columns (analytical) NUCLEOSHELL ® RP 18, 5 µm, 4 x 3 mm

Configured for stable performance in synthesis settings, pre-column systems for HPLC such as the Hplc Guard Columns (Analytical) Nucleoshell ® Rp 18, 5 μm, 4 x 3 mm, are essential for protecting your main HPLC column from contamination. Featuring a 3 mm inner diameter and 4 mm length, these guard columns are designed to prevent chemical impurities from reaching the main column, thereby extending its lifespan. With a pore size of 90 Å, a particle size of 5 μm, and a specific surface area of 90 m²/g according to BET, these core-shell, superficially porous particles (SPP) offer excellent separation efficiency. Furthermore, they are end-capped, ensuring high pH stability ranging from 1.0 to 11.0,
