Produced for stability across temperature-sensitive applications, the Hplc Guard Columns (Analytical) Nucleodur ® C 8 Gravity, 3 μm, 4 x 3 mm offer effective protection against contaminants in high-performance liquid chromatography (HPLC). With a pore size of 110 Å, a pore volume of 0.9 ml/g, and a specific surface area of 340 m²/g, these guard columns ensure optimal separation efficiency while maintaining pressure stability up to 400 bar. Their base deactivated (BDS), high-density monomeric octyl (C 8 , MOS) modified surface chemistry provides excellent compatibility with acetonitrile-water eluents, ensuring reliable performance within a wide pH range of 1.0 - 11.0 and temperatures up to 60 °
