“…includes several representative examples of the reported MOF-based coatings for this SPME geometry together with other configurations [48][49][50][51][61][62][63][64][65][66][67][68][69][70][71][72][73][74][75][76]. The vast majority of reported MOF-based f-SPME devices uses the most common MOFs, such as: HKUST-1-composed of copper nodes and 1,3,5-benzenetricarboxylate struts [61,65,[77][78][79]; UiO-66-formed by the combination of Zr clusters and 1,4-benzenedicarboxylate ligands [62,67,80,81]; MIL-type MOFs, synthesized using 1,4-benzenedicarboxylate ligands and different metal ions, including Cr [68,69,82,83], Fe [84][85][86][87], and Al [66,88]; and MOFs composed of Zn metal centers, including MOF-5 with 1,4-benzenedicarboxylate as ligand [64,[89][90][91][92], and the family of ZIF MOFs containing imidazolate-based ligands ...…”

Metal–Organic Frameworks as Key Materials for Solid-Phase Microextraction Devices—A Review

Metal–organic frameworks (MOFs) have attracted recently considerable attention in analytical sample preparation, particularly when used as novel sorbent materials in solid-phase microextraction (SPME). MOFs are highly ordered porous crystalline structures, full of cavities. They are formed by inorganic centers (metal ion atoms or metal clusters) and organic linkers connected by covalent coordination bonds. Depending on the ratio of such precursors and the synthetic conditions, the characteristics of the resulting MOF vary significantly, thus drifting into a countless number of interesting materials with unique properties. Among astonishing features of MOFs, their high chemical and thermal stability, easy tuneability, simple synthesis, and impressive surface area (which is the highest known), are the most attractive characteristics that makes them outstanding materials in SPME. This review offers an overview on the current state of the use of MOFs in different SPME configurations, in all cases covering extraction devices coated with (or incorporating) MOFs, with particular emphases in their preparation.

“…Examples of SBSE applications include determination of volatile compounds in cooked cured pork ham [145], volatile organic compounds in human urine, and water samples [146], organic pollutants in water samples [147], free fatty acids in the exudates of cooked ham [148], barbiturates in urine [149], coffee volatiles in roasted Arabica coffee [150], organic pollutants in water samples [151] and odorous compounds in drinking water [152]. Recently, SBSE has been used for enhanced recovery of pesticides in wines and aromatic compounds in beers [153] and selective enrichment and analysis of polychlorinated biphenyls in fish [154].…”

Preparing a sample for analysis is a crucial step of many analytical procedures. The goal of sample preparation is to provide a representative, homogenous sample that is free of interferences and compatible with the intended analytical method. Green approaches to sample preparation require that the consumption of hazardous organic solvents and energy be minimized or even eliminated in the analytical process. While no sample preparation is clearly the most environmentally friendly approach, complete elimination of this step is not always practical. In such cases, the extraction techniques which use low amounts of solvents or no solvents are considered ideal alternatives. This paper presents an overview of green extraction procedures and sample preparation methodologies, briefly introduces their theoretical principles, and describes the recent developments in food, pharmaceutical, environmental and bioanalytical chemistry applications.

Abstract:The extraction yield of a microextraction technique depends on thermodynamic and kinetics factors. Both of these factors have been the focus of intensive research in the last few years. The extraction yield can be increased by synthesizing and using novel materials with favorable distribution constants (one of the thermodynamic factors) for target analytes. The extraction yield can also be increased by improving kinetic factors, for example, by developing new extraction modes. Microextraction techniques are usually non-exhaustive processes that work under the kinetic range. In such conditions, the improvement of the extraction kinetics necessarily improves the performance. Since the extraction yield and efficiency is related to how fast the analytes diffuse in samples, it is crucial to stir the sample during extraction. The stirring can be done with an external element or can be integrated with the extraction element in the same device. This article reviews the main recent advances in the so-called extraction/stirring integrated techniques with emphasis on their potential and promising approaches rather than in their applications.
