HPLC Guard Columns (analytical) NUCLEODUR ® C 18 Gravity, 5 µm, 4 x 2 mm

Formulated to support synthetic operations, the Hplc Guard Columns (Analytical) Nucleodur ® C 18 Gravity, 5 μm, 4 x 2 mm are designed as pre-columns to protect the primary HPLC column from contaminants during liquid chromatography analysis. Featuring a base deactivated (BDS), high density octadecyl (C 18, ODS) modification, these short columns have a specific surface area of 340 m²/g, a pore size of 110 Å, and a pore volume of 0.9 ml/g. With a particle size of 5 μm, they offer a pressure stability of up to 600 bar and a carbon content of 18%. Ideal for use with acetonitrile-water eluents, these guard columns ensure optimal separation performance while
