TL;DR: This Account summarizes the research on the analytical applications of MOFs ranging from sampling to chromatographic separation, and develops an in situ hydrothermal growth approach to fabricate thin films of MOF-199 on etched stainless steel wire for solid-phase microextraction of volatile benzene homologues with large enhancement factors and wide linearity.

TL;DR: A zeolitic imidazolate framework-8 (ZIF-8) nanocrystal coated capillary is shown not only to have a strong ability to sieve branched alkanes from linear alkane isomers but also to offer excellent features for high-resolution gas chromatographic separation oflinear alkanes due to van der Waals interaction between linear alkanes and the hydrophobic inner surfaces of the micropores.

TL;DR: The developed tandem ZIF-8 molecular sieves were further used for the determination of linear alkanes in petroleum-based fuel and human serum and to solve headache problems in complex real sample analysis.

TL;DR: The fabrication of MOF UIO-66 coated capillary column is reported and exploration of the reverse shape selectivity and molecular sieving effect of such column for capillary gas chromatographic separation of alkane isomers and benzene homologues is explored with excellentSelectivity and precision.

TL;DR: In this article, a metal-organic frameworks (MOFs) material-based series molecular sieve and a preparation method and an application method thereof in complex sample purification and separation analysis are presented.
