Prepared for use in regulated laboratory conditions, the pre-column system for HPLC, specifically the Hplc Guard Columns (Analytical) Nucleodur ® Sioh, 3 μm, serves as a protective measure for your primary HPLC column against contamination. With a particle size of 3 μm and a pore size of 110 Å, these short columns are designed to intercept chemical impurities before they reach the main column, thereby extending its lifespan. The Nucleodur ® Sioh columns feature unmodified high purity silica gel (SiOH) as their surface chemistry, ensuring multi-mode (NP and RP), normal phase (NP) separation principles. Additionally, these columns offer a temperature stability of up to 60°C and pressure stability of 600 bar, making them suitable for various experimental conditions. For
