Evaluating Particle Size and Back Pressure in Peptide Mapping by UHPLC

Ultrahigh-pressure liquid chromatography (UHPLC) columns are used in peptide mapping to improve the resolution of highly complex peptide mixtures. It is commonly assumed that small particle columns increase performance, but this is not always the case. This study presents a comparison of peak count, column length, and resolution between core–shell and fully porous UHPLC columns.
