ReproSil-Pur 120 C18-AQ is a silica-based HPLC column with octadecyl bonded chemistry, specially modified for full aqueous compatibility. Built on high-purity 120 Å silica, this phase is designed to maintain stability and reproducibility under 100% aqueous mobile phases, avoiding phase collapse often observed with conventional C18 columns.
The hydrophilic endcapping ensures retention of highly polar analytes while maintaining strong hydrophobic interactions for nonpolar compounds. This makes ReproSil-Pur 120 C18-AQ a versatile tool for laboratories requiring reliable separations of complex mixtures across a wide polarity range.
ReproSil-Pur 120 C18-AQ combines robust hydrophobic retention with full aqueous stability – the dependable choice for laboratories analyzing polar compounds in reversed-phase HPLC.
