An investigation into the use of core–shell particle columns for separation of short (∼21 base pairs) RNA oligonucleotides by ion-pair reversed-phase liquid chromatography (IP-RPLC) showed improved resolution for a number of test analytes relative to conventional (fully-porous) reversed-phase columns. The best resolutions were obtained using columns packed with smaller sub-2 μm core–shell particles.
► Oligonucleotide analysis by ion-pair reversed-phase liquid chromatography.
► Evaluation of different fused-core columns for oligonucleotide analysis.
► Fused-core columns provided improved separations of oligonucleotides.
► The sub-2 μm particle fused-core columns showed the best separations.
► Long term column stability was tested for fused-core columns.
