SPME methods are now extremely popular. Recent advances in SPME have focused on the development of new materials as sorbent coatings capable of providing high extraction efficiencies, as well as high selectivity with high mechanical and chemical stability. Metal-organic frameworks (MOFs) have become an extremely popular material due to their unique properties (large surface area, selective gas adsorption, tunable structures, high thermal and chemical stability). This review summarizes the current status of MOF use in terms of fiber preparation, extraction performance and the applicability of SPME in air sample analysis. The analytical performance of MOF-based SPME fibers in the described air analysis applications is characterized by high extraction efficiency, adequate reproducibility, high sensitivity and acceptable reusability. In comparison with commercial coatings, MOF-based fibers tend to have better performance. Nearly all reported applications focused on HS testing and in all cases in combination with GC.
