“…However, to avoid formation of bubbles in the acceptor and donor solvents, the temperature should be considerably below 100°C. The bubbling of the acceptor solvent in MMLLE has been observed to begin at about 20°C below its boiling point [41]. It is also advisable to keep the temperature below 100°C because of the thermolability of the membrane material.…”

Pressurised hot water extraction (PHWE) was coupled on-line with microporous membrane liquid-liquid extraction (MMLLE) and gas chromatography (GC) in the analysis of polycyclic aromatic hydrocarbon (PAH) compounds in soil. The MMLLE serves as a trapping device after the PHWE. Water from PHWE is directed to the donor side of the membrane unit and the analytes are extracted to the acceptor solution on the other side of the membrane. The role of MMLLE is to clean and concentrate the extract, which is then transferred on-line to the GC via a sample loop and an on-column interface using partially concurrent solvent evaporation. Separate optimisation of MMLLE and simulations of the PHWE-MMLLE connection were carried out before the actual on-line coupling. After optimisation of the whole on-line system, the efficiencies of the PHWE-MMLLE-GC and PHWE-solid-phase trap extractions were compared. The PHWE-MMLLE-GC method allowed on-line analysis of soil samples. The method was linear, with limits of detection in the range 0.05-0.13 ng and limits of quantification 0.65-1.66 microg g(-1). Comparison of the results with those obtained by other techniques confirmed the good performance.

“…As regards sample preparation, SPE [3,4], SPME, stir bar sorptive extraction [5], microporous membrane LLE [6], PLE [7], dispersive liquid-liquid microextraction [8][9][10], and QuEChERS [9,10] are some of the many sample preparation techniques used for the extraction of pesticides and sample cleanup. Matrix solid-phase dispersion (MSPD) is also employed for the determination of pesticide residues in foodstuff [11] since it offers an excellent alternative to conventional sample preparation techniques.…”

A novel procedure is put forward based on the combination of the well-established matrix solid-phase dispersion and the magnetic and sorption properties of magnetic octadecyl in the presence of n-octanol and was employed in a proof-of-concept sample preparation and determination of several classes of pesticide residues in carrots. The procedure does not require the transfer of blend to cartridge and subsequent packing, nor any co-sorbent for extract clean up. The hydrophobic magnetic nanoparticles utilized as a sorbent, can be retrieved by n-octanol under the application of a magnetic field due to hydrophobic interactions. Elution of pesticide residues is then carried out with an organic solvent. A total of 26 pesticides were included in this procedure and the target compounds were analyzed using gas chromatography with mass spectrometry in the selective ion monitoring mode. The average extraction recoveries obtained from carrot samples fortified at three different concentrations (20, 50, and 500 μg/kg) were 77-107%. The estimated limits of quantitation for most target analytes were in the low μg/kg level. The study demonstrates that the proposed extraction procedure is simple and effective, avoiding a clean-up step for the sample preparation of vegetable.

“…Gas chromatography (GC) with various detectors including flame ionization detector (FID) [13,14], electron capture (ECD) [15], nitrogen-phosphorus detection (NPD) [15,16], mass spectrometric detector (MS) [7,8,17], tandem mass spectrometry (MS/MS) [5], capillary liquid chromatography coupled with diode array detection (cHPLC-DAD) [3], ultra-high pressure liquid chromatography coupled to MS/MS (UHPLC-MS/MS) [4] and liquid chromatography with MS/MS (LC-MS/MS) [18] have been used for determination of pesticides residues in wine. UHPLC-MS/MS [4], GC-ECD, GC-MS [19] and LC-MS/MS [20] were reported for determination of pesticide residues in beer [20].…”

“…However, SPME is expensive, uses fragile and easily broken fibres, has limited lifetime and sometimes sample carry-over could be a problem [23]. Other sample preparation methods such as supported liquid membrane (SLM) [9], microporous membrane liquid-liquid extraction (MMLLE) [13,14], hollow-fibre liquid phase microextraction (HF-LPME) [4], ultrasound-vortex-assisted dispersive liquid-liquid microextraction (USVA-DLLME) [16], dispersive liquidliquid microextraction (DLLME) [6] and quick, easy, cheap, effective, rugged and safe (QuEChERS) [6] as well as dispersive solid-phase extraction (d-SPE) [17] have also been reported for analysis of pesticide multiresidues in alcoholic beverages. Though, these procedures are relatively simple, rapid, cheap and attractive alternative for sample preparation, they are still demanding special equipment, reagents and/or toxic organic solvents.…”

Abstract:A salting-out assisted liquid-liquid extraction (SALLE) method followed by high-performance liquid chromatography with ultraviolet-visible detector (HPLC-UV/Vis) has been proposed for determination of five multiclass pesticides residues including, atrazine, ametryn, terbutryn, carbaryl and chlorothalonil from various alcoholic beverages: beer, wine and Ethiopian honey wine (Tej). Experimental parameters influencing the extraction efficiency of the method such as the type and concentration of salt, volume of acetonitrile (the extraction solvent) and pH of the sample were assayed and the optimum conditions were established. Under the optimum experimental conditions, matrix-matched calibration curves were constructed using beer sample as the representative matrix and good linearity over wide concentration ranges were obtained with coefficient of determination (r 2 ) of 0.997 or better. The limits of detection (LOD) and quantification (LOQ) of the method, which were determined as 3 and 10 times a signal-to-noise ratio (S/N), were in the ranges of 1.3-3.9 and 4.5-12.8 µg L -1 , respectively. Precisions studied in terms of repeatability and intermediate precision (with-in lab reproducibility) at two concentration levels have demonstrated acceptable %RSD values, which were less than 10% in both cases. The applicability of the method was also investigated by analyzing various alcoholic beverages and demonstrated satisfactory recoveries in the ranges of 71-104% with their corresponding %RSDs less than 10% in all cases. The results of the study revealed that the developed SALLE method is selective and efficient sample preparation procedure prior to quantitative analysis of the target analytes by HPLC-UV/Vis.
