“…It allows the compounds extracted to be separated into groups, adjusting the operating conditions such as the type and proportion of the modifier, the chelating agent added, variation in temperature/pressure, etc. [64,67]. The three major types of collection, in a solvent, on a solid-phase trap and online coupling to a chromatograph, all require quite extensive optimisation procedures.…”

“…The areas in which SFE has been more widely developed in terms of analytical applications include environmental analysis (soils and sediments) and the analysis of food products (vegetables, fruits, cheese, fat animal, feed, fish) [16,17,24,44,54,67,68]. Moreover, there are many references in the literature that demonstrate the applicability of the SFE technique to determine the existence of POPs in several complex matrices: PCBs, PCDDs and OCPs (organochlorinated pesticides) in soils, sediments and fly ashes [19,62,67,69], pesticide residues (OCPs, pyrethroids and organophosphorus pesticides, OPPs) and PCBs in food [15,65,70], human blood and tissues [65], pyrethroid pesticides in plants and seeds [24] or PCBs, PBBs, PBDEs, PCDDs, PCDFs and OCPs in biota and animal tissues [4,13,19,67,69].…”

ReviewSupercritical fluid extraction of polyhalogenated pollutants from aquaculture and marine environmental samples: A review This article focuses on the state-of-the-art in sample preparation using supercritical fluid extraction (SFE), to monitor the content of polyhalogenated pollutants in aquaculture and marine environmental samples. Marine sediments and biological applications, including several types of samples matrices (fish, shellfish, seaweed and fish feed) and analyte groups (polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), polybrominated diphenylethers (PBDEs), polychlorinated dibenzop-dioxin (PCDD)/Fs and organochlorinated pesticide (OCPs)) are discussed with respect to SFE use and optimisation of conditions. We also discuss the great analytical potential of SFE, the integration of the extraction and clean-up steps for rapid sample processing justifying its use for routine work. The most recent SFE applications to the determination of these pollutants in marine environmental (biota and sediment) samples, published in the last 15 years, are reviewed.

“…The analytes can be collected into an empty vessel, to a vessel containing a small volume of organic solvent, to a solidphase trap, or into a cryogenically cooled capillary. 6,7 Some studies were performed using reverse osmosis membranes for separation of supercritical fluid and analytes. [8][9][10] In the case of solid-phase trap, the sample is reconstituted with a rinse solvent which, containing sample fractions, is washed to the output vials.…”

Recovery of Bidens tripartita L. volatiles using supercritical CO 2 extraction with solid-phase trap was performed in this study. Three aspects were under investigation: the impact of solvent (heptane, methanol or acetonitrile) applied to rinse the analytes from the trap; the impact of the amount of plant material used for extraction; the release of volatiles from plant matrix using multiple extraction. α-Pinene, p-cymene, β-ocimene, and β-elemene were predominant in all extracts prepared in different ways. β-ocimene was the major compound (40-46%) in all extracts regardless of the solvent used. No significant difference in amount of α-pinene was observed when different trap desorption solvents were used, while heptane desorbed significantly higher amounts (12-31%) of other compounds. The volatile composition showed both qualitative and quantitative differences when different amounts of sample material were used. The extraction extent of the main compounds varied between first and repeated extractions.

“…As extraction methods, Soxhlet extraction [6][7][8] and sonication extraction (SE) 18,19 have been widely used. Recently, Soxhlet extraction that requires overnight extraction and large amount of organic solvents is being replaced by rapid extraction methods such as pressurized liquid extraction (PLE), 20,21 microwave-assisted extraction (MAE), 22,23 supercritical fluid extraction (SFE) 24 and sonication extraction (SE). During the extraction of chlorostyrenes in biological tissue, large quantities of lipids may get inevitably co-extracted with targets due to their high solubility in organic solvents.…”

An analytical method has been developed for measuring chlorostyrenes in fish tissue sample. Extraction of chlorostyrenes from fish tissue was carried out by ultrasonication using acetone/n-hexane (5:2, v/v) mixture. Most of the lipids in the extract were eliminated by freezing-lipid filtration, prior to solid-phase extraction (SPE) cleanup. During freezing-lipid filtration, about 90% of the lipids extracted from the fish samples were easily removed without any significant losses of chlorostyrenes. For purification, SPE using Florisil was used for the rapid and effective cleanup. Quantification was performed using gas chromatography-mass spectrometry in the selected ion monitoring mode. Spiking experiments were carried out to determine the recovery, precision, and limits of detection (LODs) of the method. The overall recovery was above 80% in the spiked fish tissue sample at 10 and 100 ng/g levels, respectively. The detection limits for chlorostyrenes were ranged from 0.05 to 0.1 ng/g. This developed method is demonstrated to give efficient recoveries and LODs for detecting chlorostyrenes spiked into fish tissue with high lipid content.
