Produced for stability across temperature-sensitive applications, pre-column systems like the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Gravity, 1.8 μm, 4 x 3 mm, play a crucial role in protecting your main HPLC column from contamination. Featuring a base deactivated (BDS), high density octadecyl (C 18, ODS) modification, these columns provide excellent separation principles through reversed phase (RP) mechanisms. With a specific surface area of 340 m²/g, they offer a large active surface area for efficient sample analysis. Additionally, their fully porous particle structure ensures optimal pore volume (0.9 ml/g) and pore size (110 Å), while maintaining a pressure stability of up to 800 bar. By using these guard columns, you can significantly
