EC HPLC precolumn (analytical), NUCLEOSHELL Biphenyl, 2.7 µm, 4×3 mm

Description

Hydrophobic phase with alternative selectivity compared to classic C18 modifications. The separation principle is based on two retention mechanisms – π-π and hydrophobic interactions. This results in better retention of aromatic and unsaturated substances. This stationary HPLC phase is based on high-purity NUCLEODUR silica gel and shows excellent performance under very aqueous conditions.
