Designed with efficiency in synthetic processes in mind, the Hplc Column Nucleodur® C 18 Gravity SB offers exceptional performance under highly aqueous conditions. This analytical separation column features a C 18 Gravity SB phase, known for its distinct polar selectivity that ensures better retention of early eluting substances. Made of high purity NUCLEODUR® silica gel, it exhibits excellent performance even under challenging conditions such as those encountered in liquid chromatography (LC, HPLC). Its low bleeding characteristics make it suitable for LC/MS applications. With a recommended use in overall sophisticated analytical separations, particularly for polar compounds like antibiotics, organic acids, water-soluble vitamins, and ideal for method development, this column is an indispensable tool for any lab specializing in chromatography.
