HPLC Guard Columns (analytical) NUCLEODUR ® CN

Structured to assist in consistent experimental procedures, the Hplc Guard Columns (Analytical) Nucleodur ® CN are designed as pre-column systems for high-performance liquid chromatography (HPLC). With a pore size of 110 Å, a particle size of 5 µm, and a specific surface area of 340 m²/g, these guard columns provide effective filtration against potential contaminants before they reach the main HPLC column. Featuring fully porous particles (FPP), a carbon content of 7 %, and a cyano, nitrile (CN) surface chemistry, these guard columns offer multi-mode separation principles, including normal phase (NP), making them suitable for various analytical applications. The guard columns have a pressure stability of up to 600 bar, a temperature stability of 60 °C, and an eluent in
