Optimized for controlled laboratory processes, the Hplc Guard Columns (Analytical) Nucleodur ® Π 2, 5 μm, 4 x 3 mm are designed to protect your main HPLC column from contamination during liquid chromatography analysis. Featuring fully porous particles (FPP), a biphenylpropyl modification surface chemistry, and a pore size of 110 Å, these guard columns effectively filter out chemical impurities before they reach the main column, extending its lifespan. With a specific surface area of 340 m²/g, a pH stability range of 3.0-10.0, and a pressure stability of up to 600 bar, these guard columns ensure reliable performance under various conditions. Ideal for analytical applications, these pre-column systems for HPLC are part of a comprehensive offering
