Manufactured to meet research and production requirements, the Hplc Guard Columns (Preparative) Nucleodur ® C 18 Pyramid, 10 x 8 mm, serve as essential pre-column systems for high-performance liquid chromatography (HPLC). Placed within a guard column holder, they protect the primary HPLC column from contaminants, extending its lifespan. Featuring fully porous particles (FPP), octadecyl (C 18, ODS) modification, polar endcapping, and a pore size of 110 Å, these guard columns ensure optimal separation performance under pressures up to 400 bar. With a specific surface area of 340 m²/g, a carbon content of 14 %, and a pore volume of 0.9 ml/g, they provide exceptional capacity for various
