Developed for demanding processing applications, pre-column systems for HPLC such as the HPLC Guard Columns (Analytical) Nucleodur ® Hilic offer essential protection for your main HPLC column. With a particle size of 3 μm and a pore size of 110 Å, these short columns feature fully porous particles (FPP), ammonium – sulfonic acid (zwitterionic) modification, and a specific surface area of 340 m²/g according to BET. Designed for hydrophilic interaction chromatography (HILC), they boast a pressure stability of 600 bar and a temperature stability of 60 °C. Ideal for use with acetonitrile – water eluents, these guard columns ensure optimal performance and longevity for your main HPLC column.
