ReproSil-Pur 120 C4 is a silica-based HPLC column with butyl bonded chemistry on high-purity 120 Å silica. With shorter alkyl chains than C8 or C18 phases, it provides moderate hydrophobic retention, making it well suited for analytes that require reduced retention times or complementary selectivity in method development.
The 120 Å pore size is optimized for small to medium-sized molecules, while the robust bonding chemistry ensures reproducibility, sharp peak shapes, and long operational lifetimes. ReproSil-Pur 120 C4 is a versatile option for pharmaceutical, biochemical, and environmental laboratories.
ReproSil-Pur 120 C4 provides balanced hydrophobic retention and robust performance – the dependable choice for laboratories requiring flexible reversed-phase HPLC separations.
