“…As can be seen, compared with other SPME coatings, including periodic mesoporous organosilica based on alkylimidazolium ionic liquid (PMO-IL) [38], PDMS [39], PDMS/DVB [40] and graphene [41], the prepared PDMS/MIL-101 coated fiber exhibited faster extraction kinetics for the PAHs. The LODs of the developed method was lower than that obtained by μ-SPE …”

“…Electrodeposition of aniline at the presence of ILs in aniline solution could prepare fibrous nanostructured polyaniline-IL composites, which were also stable for repeated uses [51,52]. Abolghasemi et al [53] prepared IL-based periodic mesoporous organosilica (PMO-IL) and glued PMO-IL on a SSW to prepare a SPME fiber. Other two studies used ILs as porogens in sol-gel processes, where ILs were actually not used as coating materials [54,55].…”

The basic principles for the preparation of SPME fibers with satisfying selectivity, sensitivity, loading capacities and stabilities are summarized here in terms of the physicochemical properties of the coating materials and the supporting substrates of SPME fibers. While the main part of this chapter focuses on the advances in developing the most widely used coating materials, including ionic liquids, polymeric ionic liquids, carbonaceous materials, molecularly imprinted polymers, metal-organic frameworks, metals and metal oxides, conductive polymers, modified silica, as well as their composites, into SPME fibers. Meanwhile, the applications of novel SPME fibers in analyzing diverse analytes in different sample matrices are briefly reviewed, including the emerging applications of SPME in the extraction of bioactive compounds in living animals and plants.Keywords SPME fiber coating Á Ionic liquid Á Polymeric ionic liquid Á Graphene Á Carbon nanotube Á Molecularly imprinted polymer Á Metal-organic framework Á Metal and metal oxide Á Conductive polymer Á Modified silica IntroductionThe outstanding features of solid-phase microextraction (SPME), including rapid and simple operating procedures, slight disturbance to investigated systems, reduced consumption of solvents, and feasibility of automation, continuously inspire new explorations of SPME in various frontiers, such as metabolome detection [1], central nervous systems studies [2], pharmacokinetic studies [3], environmental analysis [4], and food analysis [5].

“…Nowadays, SPME is among the most recommended techniques, employed for the extraction and preconcentration of volatile and semi‐volatile compounds at trace levels in the different matrices. This technique has important advantages over conventional extraction techniques because of its ease of use, and portable and solvent free nature . Although SPME has demonstrated extraordinary versatility in sampling capabilities, the technique continues to experience a tremendous growth in innovation.…”

We have synthesized an organic-inorganic polyaniline-halloysite nanotube composite by an in situ polymerization method. This nanocomposite is immobilized on a stainless-steel wire and can be used as a fiber coating for solid-phase microextraction. It was found that our new solid-phase microextraction fiber is an excellent adsorbent for the extraction of some volatile organic compounds in aqueous samples in combination with gas chromatography and mass spectrometry. The coating can be prepared easily, is mechanically stable, and exhibits relatively high thermal stability. It is capable of extracting phenolic compounds from water samples. Following thermal desorption, the phenols were quantified by gas chromatography with mass spectrometry. The effects of extraction temperature, extraction time, sample ionic strength, stirring rate, pH, desorption temperature and desorption time were studied. Under optimal conditions, the repeatability for one fiber (n = 5), expressed as the relative standard deviation, is between 6.2 and 9.1%. The detection limits range from 0.005 to 4 ng/mL. The method offers the advantage of being simple to use, with a shorter analysis time, lower cost of equipment and higher thermal stability of the fiber in comparison to conventional methods of analysis.
