Flow-dependent separation selectivity for organic molecules on metal–organic frameworks containing adsorbents

A new flow-dependent separation selectivity (FDSS) effect was discovered in isocratic HPLC. Significant changes in chromatographic selectivity were achieved by simple variation of the mobile phase flow rate. The FDSS effect was observed for a core–shell stationary phase using silica particles as a core and a Zr-based metal–organic framework (UiO-66) as a shell.
