The diverse structures and pore topologies, accessible cages and tunnels, and high surface areas make metal-organic frameworks attractive as novel media in separation sciences. Here we report the slurry-packed MIL-101(Cr) column for high-performance liquid chromatographic separation of substituted aromatics. The
