“…Following the trends of analytical chemistry on miniaturization, several approaches of sorbent microextraction have been developed such as solid-phase microextraction (SPME) [7][8][9], stir-bar sorptive extraction (SBSE) [10], thin film microextraction (TFME) [11] and related techniques as well as magnetic solid-phase extraction (MSPE) [12]. Despite the fact that SPME is a well-established microextraction technique, in some applications, it may not provide the desired sensitivity due to the small sorbent mass and sample capacity as well as mechanical distortion resulting in poor precision and sensitivity [13].…”

Since the introduction in 2014 of fabric phase sorptive extraction (FPSE) as a sample preparation technique, it has attracted the attention of many scientists working in the field of separation science. This novel sorbent extraction technique has successfully utilized the benefits of sol-gel derived hybrid sorbents and a plethora of fabric substrates, resulting in a highly efficient, sensitive and green sample pretreatment methodology. The proposed procedure is an easy and efficient pathway to extract target analytes from different matrices providing inherent advantages such as high sample loading capacity and short pretreatment time. The present review mainly focuses on the background and sol-gel chemistry for the preparation of new fabric sorbents as well as on the applications of FPSE for extracting target analytes, from the time that it was first introduced. New modes of FPSE including stir FPSE, stir-bar FPSE, dynamic FPSE, and automated on-line FPSE are also highlighted and commented upon in detail. FPSE has been effectively applied for the determination of various organic and inorganic analytes in different types of environmental and biological samples in high throughput analytical, environmental, and toxicological laboratories.

“…Several new extraction-separation techniques suitable for the use with low amounts of the sample were designed recently. Among them, microextraction by packed sorbent (MEPS™; SGE Analytical Science, Australia), which is a small-scale format of a classic solid-phase extraction, offers both polar and hydrophobic sorbents and is well suited to be used with chromatographic systems [16][17][18]. Reusable sorbent bed is integrated into a syringe, which may be used either manually or automatically to process the small volume (10 μL or more) of the liquid sample.…”

Summary.The microextraction by packed sorbent (MEPS) was applied to a fractionation of cuticular wax extracts from several solanaceous plant species. A procedure developed requires only 0.6 mL of organic solvents and may be completed in less than 10 min. Hydrocarbons, which are frequently used in chemotaxonomy of Solanaceae, were almost exclusively eluted in one fraction. The amounts of most commonly detected polar wax components (alcohols, sterols, triterpenes) in the same fraction were reduced to ca. 34-46% of the total amounts in the whole extract. Despite the contamination of the hydrocarbon fraction with other wax components, the results obtained using MEPS and standard column chromatography on silica gel were similar when compared using cluster analysis based on the hydrocarbon profiles. However, the method was far less successful in removing the sucrose esters from extracts of Nicotiana rustica leaves. Thus, MEPS fractionation of plant cuticular waxes may be a fast and reliable alternative for the standard liquid chromatography techniques as long as no sucrose esters are present in the extract.

“…Most of commercially available fibers are nonpolar, and the other relatively polar ones strongly suffer from lack of thermal stability [17]. The low extraction efficiency of highly polar compounds is still a problem that limits the application of SPME [20]. Therefore, there is still the need for new coating materials that allow better affinity for a broad group of polar organic compounds.…”

“…Sol-gel technology has been widely used to prepare SPME fibers [18,19] because it can effectively create chemically bonded, porous, and highly crosslinked coatings on the fused silica fiber surface. Liu et al [20] developed a new aluminabased organic-inorganic sol-gel coating for SPME of polar compounds. It was shown that the presence of alumina in the coating provides Lewis acid sites, which improve the extraction performance of the proposed fiber in SPME of small polar molecules.…”

A New Aluminium Hydroxide Coating on Fused Silica Fiber for the Determination of 1,4-Dioxane in Surfactants and Detergents Using HS-SPME-GC

et al. 2012

This paper presents a simple and convenient analytical method for determination of 1,4-dioxane in surfactants and detergents by using a novel SPME fiber. For the preparation of the fiber, the surface of a fused silica capillary tubing was modified by means of aluminium tritert-butoxide in a straightforward grafting process. The surface of our proposed fiber provides a Lewis acid-base interaction with analyte functional groups. The main factors affecting the extraction were optimized by using a central composite design method, which leads to the following optimum conditions: extraction temperature of 34°C, extraction time of 4 min, equilibrium time of 13 min, and salt content of 25% (w/v). The optimum conditions showed a linear range from 0.005 to 60 lg g -1 . LOD and LOQ of the proposed method were estimated to be 0.0015 and 0.005 lg g -1 , respectively. This method was also applied for the analysis of some real samples including ethoxylated fatty alcohol, sodium lauryl ether sulfate, dish-washing agents, and shampoos by using the standard addition method.
