ReproSil 100 ODS-AQ from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 100 Å pore size and an aqueous-compatible octadecylsilane bonded phase. Specially engineered to maintain hydrophobic retention in highly aqueous mobile phases, this column is ideal for the separation of polar analytes that would otherwise elute too early on conventional C18 phases. The ODS-AQ bonding prevents phase collapse in 100% aqueous eluents, delivering excellent reproducibility, sharp peak shapes, and enhanced selectivity for hydrophilic compounds.
ReproSil 100 ODS-AQ columns from Dr. Maisch HPLC GmbH provide reliable aqueous-phase C18 performance – the perfect choice for polar compound chromatography in reversed-phase HPLC.
