Ultrasep ES 100 RP3 is a silica-based HPLC column with a 100 Å pore size and a C3 (propyl) bonded phase. The short alkyl chain provides low to moderate hydrophobic retention, enabling faster elution than C8 or C18 columns while still offering better retention than C1 phases. This makes it a versatile option for analytes that are strongly retained on longer alkyl chains.
With its excellent reproducibility, sharp peak symmetry, and robust performance, RP3 is well-suited for both routine QC analysis and method development requiring alternative selectivity.
Ultrasep ES 100 RP3 combines fast elution with reproducible selectivity – the reliable choice for efficient reversed-phase HPLC separations.
