WebFeb 15, 2013 · Results showed a marked superiority of the HILIC/SALT approach compared to traditional HILIC and excellent complementarity to RPC for peptide separations. We believe these initial results offer a new dimension to HILIC, enabling it to transform from an occasional HPLC approach for peptide separations to a more generally applicable method. Webpeptide separation INTRODUCTION Liquid chromatography (LC) is commonly used for the separation and analysis of hydrophilic and highly polar analytes. Supercritical fluid chromatography (SFC) began to develop in this direction too and pushed the limits of chiral and achiral separations.
