EC HPLC Guard Column, NUCLEOSHELL RP 18plus, 4 x 3 mm, 2.7 µm, 3/pk

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.
