Designed for professional use, the pre-column systems for HPLC, specifically the Nucleoshell® Hilic HPLC Guard Columns, are essential accessories for protecting your main HPLC column from contamination. With a length of 4mm, an inner diameter of 2mm, and a particle size of 2.7µm, these core-shell, superficially porous particles (SPP) columns are designed to prevent chemical impurities from reaching the main column. Featuring ammonium – sulfonic acid (zwitterionic) modification and a pore size of 90 Å, they operate under a pressure stability of 600 bar and have a specific surface area of 130 m²/g. Ideal for hydrophilic interaction chromatography (HILC), these guard columns are compatible with acetonitrile - water eluents and have a
