Suitable for laboratory and industrial environments, the pre-column systems for HPLC, such as the Hplc Guard Columns (Analytical) Nucleodur ® Hilic, play a crucial role in protecting your main HPLC column from contamination. With a particle size of 5 μm and a pore size of 110 Å, these guard columns are designed to prevent chemical impurities from reaching the main column, thereby extending its lifespan. Featuring hydrophilic interaction chromatography (HILIC), they are particularly effective at separating polar and ionizable compounds. Additionally, their ammonium – sulfonic acid (zwitterionic) modified surface provides excellent temperature stability up to 60°C and pressure resistance up to 600 bar. Whether you're working in a research lab or an industrial setting, these guard columns offer reliable performance and dur
