HPLC Guard Columns (analytical) NUCLEODUR ® C 18 Pyramid, 1.8 µm, 4 x 3 mm

Built to deliver predictable results in synthesis routines, pre-column systems like the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Pyramid, 1.8 μm, 4 x 3 mm, play a crucial role in protecting your main HPLC column from contamination. 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 are designed to prevent chemical impurities from reaching the main column, thereby extending its lifespan. With a particle size of 1.8 μm, a pressure stability of 800 bar, and a surface chemistry of octadecyl (C 18, ODS) modification with polar endcapping, these guard columns offer exceptional performance and reliability in
