Developed for demanding processing applications, the pre-column systems for HPLC, such as the Hplc Guard Columns (Preparative) Nucleodur ® C 18 Htec, 15 x 32 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 guard columns are designed to prevent chemical impurities from reaching the main column, thereby extending its lifespan. With a pore size of 110 Å, a specific surface area of 340 m²/g, and a pressure stability of up to 400 bar, these guard columns are well-suited for reversed phase separations using acetonitrile-water eluents.
