“…Similarly, monolithic fiber has also found application in the in-tube SPME (IT-SPME) through the development of novel materials such as the MOF-monolithic adsorbent with enhanced surface area, which was successfully used to detect fluoroquinolones at ultra-trace level in river water [54], but also the development of new strategies such as magnetism-enhanced monolith-based in-tube solid-phase microextraction (ME-MB/IT-SPME). This technique used modified absorbent material with Fe 3 O 4 nanoparticles and the exertion of a variable magnetic field to overcome the main drawbacks of the traditional monolith-based in-tube solid-phase microextraction (MB/IT-SPME), that is the low extraction efficiency; this method was used for the extraction of triazines from river and lake water [85].…”

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.

“…The magnetic IT-SPME dissolved the dilemma of low extraction efficiency existing in IT-SPME, but the coating was unstable and the extraction capacity was unsatisfactory. In our previous studies [24][25][26][27] Five studied PAs including CA (≥96%), VA (≥97%), FLA (99%), DPA (98%), and HPA (98%) were obtained from ANPLE Laboratory Technologies (Shanghai, China). Supporting Information Table 1 describes the related properties of investigated PAs.…”

Magnetism-assisted in-tube solid phase microextraction based on porous monolith mingled with Fe 3 O 4 nanoparticles was developed for capture of phenolic acids in fruit juices. First, poly (1-allyl-3-methylimidazolium bis [(trifluoro methyl) sulfonyl] imide-co-ethylene dimethacrylate) monolith embedded with Fe 3 O 4 nanoparticles was facile fabrication in a capillary and employed as microextraction column. Subsequently, a magnetic coil adopted to produce variable magnetic fields during extraction stage was twined on the microextraction column. The analytes contents in eluant were quantified by high performance liquid chromatogram with diode array detector. Various parameters affecting the extraction performance were inspected and optimized in detail. Results revealed that the exertion of magnetic fields in adsorption and desorption steps enhanced the extraction efficiencies of analytes from 44.9-64.0% to 78.6-87.1%. Under the optimal extraction factors, the limits of detection were between 0.012 and 0.061 μg/L, relative standard deviations for precision in terms of intra-and inter-day assay variability ranged from 1.9 to 9.8%. The introduced approach was successfully applied to simultaneously quantify the contents of five analytes in real fruit juices with satisfying fortified recoveries (80.1-116%). The obtained results well demonstrate the promising potential of the developed method in the highly sensitive quantification of trace phenolic acids in complex samples.

“…However, the improvement of extraction performance is still worth researching. Metal-organic frameworks (MOFs) are materials that exhibit excellent characteristics, such as large specific surface areas, inherent porous structures, and high adsorption capacities [21][22][23]. MOFs have been applied for sample pretreatment and yielded exciting results; however, its use is limited because of inadequate chemical stability in moisture and inconvenient retrieval from the sample matrix [24][25][26].…”

In this study, a novel monolithic capillary column based on a NH2-MIL-53(Al) metal–organic framework (MOF) incorporated in poly (3-acrylamidophenylboronic acid/methacrylic acid-co-ethylene glycol dimethacrylate) (poly (AAPBA/MAA-co-EGDMA)) was prepared using an in situ polymerization method. The characteristics of the MOF-polymer monolithic column were investigated by scanning electron microscopy, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffractometry, Brunauer-Emmett-Teller analysis, and thermogravimetric analysis. The prepared MOF-polymer monolithic column showed good permeability, high extraction efficiency, chemical stability, and good reproducibility. The MOF-polymer monolithic column was used for in-tube solid-phase microextraction (SPME) to efficiently adsorb trace sulfonamides from food samples. A novel method combining MOF-polymer-monolithic-column-based SPME with ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) was successfully developed. The linear range was from 0.015 to 25.0 µg/L, with low limits of detection of 1.3–4.7 ng/L and relative standard deviations (RSDs) of < 6.1%. Eight trace sulfonamides in fish and chicken samples were determined, with recoveries of the eight analytes ranging from 85.7% to 113% and acceptable RSDs of < 7.3%. These results demonstrate that the novel MOF-polymer-monolithic-column-based SPME coupled with UHPLC-MS/MS is a highly sensitive, practical, and convenient method for monitoring trace sulfonamides in food samples previously extracted with an adequate solvent.
