Produced for stability across temperature-sensitive applications, the Pre-column systems for HPLC, specifically the Hplc Guard Columns (Analytical) Nucleodur ® C 8 Gravity, 5 μm, 4 x 2 mm, are designed to protect your primary HPLC column from contaminants. Featuring a base deactivated (BDS), high density monomeric octyl (C 8 , MOS) modification, these guard columns ensure optimal separation performance under various pH conditions (1.0 - 11.0). With a pressure stability of up to 600 bar and a temperature tolerance of 60°C, they provide robustness for demanding analytical tasks. Additionally, their specific surface area of 340 m²/g ensures efficient adsorption capacity, while the particle size of 5 μm provides excellent resolution. For enhanced
