Structured to assist in consistent experimental procedures, the Hplc Column Nucleodur ® C 18 Gravity Sb, 1.8 μm, 50 mm, 4 mm falls within the category of Separation columns for HPLC. This UHPLC phase features a C 18 Gravity SB hydrophobic phase with distinct polar selectivity for better retention of early eluting substances. Made of high purity NUCLEODUR ® silica gel, it exhibits excellent performance under highly aqueous conditions, making it suitable for LC/MS applications. With a pore size of 110 Å, this column is ideal for overall sophisticated analytical separations, particularly for polar compounds such as antibiotics, organic acids, water-soluble vitamins, and more. Its specific surface area according to BET is 340
