- EC HPLC column (analytical), NUCLEOSHELL RP 18plus, 5 µm, 250x3 mm
Hydrophobic C18 phase with distinct polar selectivity for better retention of early eluting substances. This HPLC phase is made of core-shell technology silica gel particles 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.
