Engineered for consistent performance, the HPLC Column Nucleodur® C 18 Pyramid, available in a 250mm x 4.6mm dimension, features fully porous particles (FPP) with a particle size of 5μm and a specific surface area of 340m²/g. This reversed phase (RP) column, with its octadecyl (C 18 , ODS) modification and polar endcapping, is suitable for aqueous eluents, making it ideal for separating very polar compounds such as pharmaceutical raw materials, analgesics, and water-soluble vitamins. With a pressure stability of up to 600 bar and temperature stability of 60°C, this column ensures reliable results under various conditions.
