“…is extraction phase is in part connected to the core, leading to additional coating and fiber endurance, whilst maintaining the flexibility of the device. Lately, Supelco has released SPME fibers based on Nitinol-core (NiTi) SPME fiber, a metal alloy-based fiber made with a material characterized by high flexibility with better inertness compared to stainless steel [41]. is thinner metal alloy provides extra flexibility, whilst the needle is reinforced thanks to the thicker alloy in the plunger.…”

The solid-phase microextraction (SPME), invented by Pawliszyn in 1989, today has a renewed and growing use and interest in the scientific community with fourteen techniques currently available on the market. The miniaturization of traditional sample preparation devices fulfills the new request of an environmental friendly analytical chemistry. The recent upswing of these solid-phase microextraction technologies has brought new availability and range of robotic automation. The microextraction solutions propose today on the market can cover a wide variety of analytical fields and applications. This review reports on the state-of-the-art innovative solid-phase microextraction techniques, especially those used for chromatographic separation and mass-spectrometric detection, given the recent improvements in availability and range of automation techniques. The progressively implemented solid-phase microextraction techniques and related automated commercially available devices are classified and described to offer a valuable tool to summarize their potential combinations to face all the laboratories requirements in terms of analytical applications, robustness, sensitivity, and throughput.

“…Conductive polymers (CPs) have been also exploited as SPME coating for the extraction of contaminants from drinking water. In particular, thermal and mechanical stability of the polypyrrole-based SPME fibers have been evaluated for the analysis of haloanisoles in tap water [113] whereas polyaniline/silver (PANI/Ag) composites were The use of carbon nanotubes (CNTs) has been exploited for the extraction of benzene derivatives [110,111], and phthalates [112] from drinking water samples. Owing to the carbon backbone provided by a two-dimensional structure with unique structural and chemical properties, CNTs are highly hydrophobic and mostly applied to extract hydrophobic analytes, through π-π stacking interactions.…”

The present review aims to describe the recent and most impactful applications in pollutant analysis using solid-phase microextraction (SPME) technology in environmental, food, and bio-clinical analysis. The covered papers were published in the last 5 years (2014–2019) thus providing the reader with information about the current state-of-the-art and the future potential directions of the research in pollutant monitoring using SPME. To this end, we revised the studies focused on the investigation of persistent organic pollutants (POPs), pesticides, and emerging pollutants (EPs) including personal care products (PPCPs), in different environmental, food, and bio-clinical matrices. We especially emphasized the role that SPME is having in contaminant surveys following the path that goes from the environment to humans passing through the food web. Besides, this review covers the last technological developments encompassing the use of novel extraction coatings (e.g., metal-organic frameworks, covalent organic frameworks, PDMS-overcoated fiber), geometries (e.g., Arrow-SPME, multiple monolithic fiber-SPME), approaches (e.g., vacuum and cold fiber SPME), and on-site devices. The applications of SPME hyphenated with ambient mass spectrometry have also been described.

“…This natural coating was supported on a nitinol (NiTi) alloy to ensure mechanical stability, high durability and corrosion resistance. 25,26 The proposed SPME fiber exhibited excellent analytical performance compared to a commercial fiber when applied to the determination of organochlorine pesticides in water samples. 24 The bract fiber represents a promising 'green' coating for solid-phase microextraction, since this biosorbent is natural, renewable and biodegradable, being obtained from Araucaria angustifolia (Bertoloni) Otto Kuntze, a coniferous tree present in southern Brazil.…”

In this study, the use of bracts as a natural sorbent in solid-phase microextraction was exploited for use in the determination of polycyclic aromatic hydrocarbons in water samples with separation/detection performed by gas chromatography-mass spectrometry. Fiber-to-fiber reproducibility was evaluated and the relative standard deviation (RSD) was lower than 14%. Optimizations were performed using both the proposed and DVB/Car/PDMS (divinylbenzene/ carboxen/polydimethylsiloxane) fibers. The optimum extraction conditions were 80 min of extraction at 50 °C with 12% (m/v) NaCl for the bract fiber, and 100 min of extraction at 80 °C for the commercial fiber. The limits of detection and quantification for the proposed fiber were, respectively, 0.003 and 0.01 µg L-1 for fluorene, phenanthrene, anthracene and pyrene, and 0.03 and 0.1 µg L-1 for acenaphthylene, benzo(a)anthracene and chrysene. The method using bract fiber provided relative recoveries ranging from 68 to 117%, intraday and interday precisions lower than 17 and 19%, respectively, and extraction efficiency similar to that of the DVB/Car/PDMS fiber.
