Designed to integrate seamlessly into laboratory operations, the Pre-column systems for HPLC, specifically the Hplc Guard Columns (Analytical) Nucleodur ® PFP, 1.8 μm, 4 x 2 mm, serve as essential protective measures for your main HPLC column. Featuring fully porous particles (FPP), a pore size of 110 Å, and a specific surface area of 340 m²/g according to BET, these guard columns prevent chemical impurities from reaching the main column, thereby extending its lifespan. With a particle size of 1.8 μm and a pressure stability of up to 900 bar, they ensure optimal performance under various conditions while maintaining a pH stability range of 1.0-9.0. The reversed phase (RP) separation principle, combined with a carbon content of
