which is much larger than that of the packed
columns. The present MIL-101 coated capillary column even
efficiently separated p-xylene and m-xylene, even though
such separation is challenging in the chemical industry
because of the similarity of their boiling points. Moreover,
only 1 mg MIL-101 was needed for the fabrication of a
capillary column, which substantially improves the cost
efficiency of MOFs in chromatographic separation.
