“…In addition, some novel materials and distinctive methods have also been explored in the preparation of SPME fibers recently. Amini et al [25] modified the fused-silica fiber with four different ionic liquid. Hashemi [26] prepared amino ethyl-functionalized nanoporous silica and used it as a novel fiber coating for SPME.…”

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].

“…Presently, increasing efforts have been directed toward the engineering of novel sorbent material in order to expand the applicability of HS-SPME for a wider range of analytes and matrices [1]. For instance, ionic liquids and their polymers were used as a novel-coating materials for SPME with excellent performance [2][3][4][5]. In addition to ionic liquids, conducting polymers, such as polypyrrole, polyaniline, and polythiophene (PT), were also successfully used for SPME coatings.…”

Nano-structured self-doped polythiophene (SPT) electrodeposited in the presence of fluorinated organic acid was applied as a thermally stable conductive polymer-based solid-phase microextraction (SPME) fiber candidate. Quantitative determination of trace levels of phthalate esters including dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), and diethylhexyl phthalate (DEHP) was carried out using this novel fiber, coupling with gas chromatography-flame ionization detector (GC-FID). The SPT coating was proved to be stable at high temperatures (∼350°C) with a high extraction capacity and long lifetime (more than 60 times). Improved temperature resistance was obtained by the presence of sulfonated groups in the backbone of polymer. Thermal stability of novel SPT was superior to common polythiophene (synthesized in LiClO(4) ). The extraction procedure was optimized by means of the Taguchi orthogonal array experimental design with an OA(16) (4(5) ) matrix including extraction temperature, extraction time, salt concentration, stirring rate, and headspace volume. The good linearity was obtained for most compounds with correlation coefficients (R(2) ) of between 0.993 and 0.995. The detection limits were lower than 0.12 ng/mL for dimethyl phthalate, DEP, dibutyl phthalate, and diethylhexyl phthalate. The method was successfully applied to the analysis of water samples with the recoveries from 90±1 to 107±1%.
