- EC UHPLC column (analytical), NUCLEODUR C18 Gravity-SB, 1.8 µm, 100x4.6 mm
Hydrophobic C18 phase with distinct polar selectivity for better retention of early eluting substances. This UHPLC phase is made of high purity NUCLEODUR silica gel and shows excellent performance under highly aqueous conditions. Due to low bleeding characteristics these columns are suitable for LC/MS. This stationary phase is used for overall sophisticated analytical separations, especially for polar compounds.
