Designed with efficiency in synthetic processes in mind, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Gravity, 3 μm, 4 x 2 mm, are ideal for protecting your main HPLC column from contamination. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of 600 bar, these guard columns ensure optimal performance and longevity of your main column. Featuring fully porous particles (FPP) and a high density octadecyl (C 18 , ODS) modification, they offer excellent separation principles through reversed phase (RP). Furthermore, their end-capping ensures stable elution conditions when using acetonitrile-water as the eluent within the column.
