HPLC Guard Columns (analytical) NUCLEODUR ® C 18 PAH, 1.8 µm, 100 Å, 4 x 2 mm

Produced to ensure dependable processing results, the pre-column systems for HPLC, such as the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Pah, 1.8 μm, 100 Å, 4 x 2 mm, are essential components in liquid chromatography (LC, HPLC). These guard columns, specifically designed with fully porous particles (FPP), protect the main HPLC column from contamination by filtering out chemical impurities before they reach the primary column. Featuring a special octadecyl (C 18 , ODS) modification and a pore size of 100 Å, these guard columns offer excellent separation performance under a wide pH range of 2.0-8.0. With a pressure stability of up to 900 bar, these guard columns can handle high pressures
