Abstract:A comprehensive review is presented on the recent developments and trends in the QuEChERS (quick, easy, cheap, effective, rugged, and safe) sample preparation approach. This technique involves liquidliquid partitioning using acetonitrile and purifying the extract using dispersive solid-phase extraction (d-SPE). Originally, the QuEChERS was introduced for pesticides residues analysis in high moisture fruits and vegetables, but more recently it is gaining significant popularity in the analysis of broad spectrum of analytes in huge variety of samples. The wide range of the technique applications is possible due to introducing various modifications based on the use of different extraction solvent and salt formulation and buffer additions for salting-out partitioning step and the application of various d-SPE sorbents for clean-up step. Therefore, the QuEChERS approach is useful for analysis of, among others pesticides, veterinary drugs and other pharmaceuticals, mycotoxins, polycyclic aromatic hydrocarbons (PAHs), dyes, acrylamide, synthetic musks and UV filters, bisphenols, polybrominated diphenyl ethers and other flame retardants, endocrine disruptors, and other chemical compounds. Thanks to the QuEChERS approach, high-throughput multiresidue methods operate in a routine contaminant control of food products, feedstuff, and environmental samples.

“…The retention mechanism of Z-Sep sorbents involves Lewis acid/base interactions. Due to its properties, it can reduce the amount of lipids and some pigments (Lozano et al 2014) and provide an optimum balance between planar pesticide recovery and color removal. ChloroFiltr is a polymeric-based sorbent designed for the removal of chlorophyll without sacrificing the recovery of planar analytes (Walorczyk et al 2015).…”

Modification of Multiresidue QuEChERS Protocol to Minimize Matrix Effect and Improve Recoveries for Determination of Pesticide Residues in Dried Herbs Followed by GC-MS/MS

An accurate, rapid, and reliable multiresidue QuEChERS method based on gas chromatography coupled with tandem mass spectrometry was developed for the determination of 235 pesticides in challenging, dry, complex herb matrices (Centaurea cyanus L., Matricaria chamomilla L., Thymus vulgaris L.). Sample mass and the type of cleanup sorbent used to estimate the procedure's effectiveness were optimized. Purification steps with ChloroFiltr, ENVI-Carb, GCB, octadecyl, PSA, and Z-Sep as cleanup sorbents and a step without purification were compared. To minimize the matrix effect and obtain acceptable recoveries for pesticides, 2 g of herb sample and 10 mL acetonitrile, followed by d-SPE cleanup step with a combination of 150 mg PSA/ 45 mg ENVI-Carb/900 mg MgSO 4 , and additionally 50 μL of 5% formic acid and some droplets of dodecane, were needed. Matrix effects for the vast majority of pesticides were reduced (> 20%), showing suppression or enhancement. Most recoveries were in the range of 70-120% (RSD < 18%), reaching the quantification limit of 0.001 to 0.002 mg kg −1 . There was excellent linearity within the range from 0.001 to 2.00 μg mL −1 , and a correlation coefficient higher than 0.999 was obtained. Expanded measurement uncertainty was estimated to be between 4 and 43%. Finally, the developed method was successfully employed to identify and quantify pesticide residues in the analysis of 46 real herb samples.

“…ZSep is a sorbent based on modified silica gel with zirconium oxide(IV), which enables Lewis acid/base interactions for efficient interferences removal (Rejczak and Tuzimski 2015b). Up to date, its potential in QuEChERS d-SPE clean-up step was tested in several matrix types, such as different fruits and vegetables (Rajski et al 2013, Lozano et al 2014, Tuzimski and Rejczak 2014, Morris and Schriner 2015, Walorczyk et al 2015, López-Blanco et al 2016, fish Lehotay 2013, Kaczyński et al 2017), edible oils (Moreno- Fig. 1 Chromatogram (λ = 260 nm) showing separation of eight sulfonylurea herbicides at concentration of 4 μg mL −1 and table showing chromatographic parameters for individual peaks (k capacity factor; Width (min) peak width at half height; A S symmetry factor; t F tailing factor; N/m theoretical plate numbers calculated by half-width method; α selectivity to proceeding peak; R S resolution to proceeding peak calculated by half-width method.…”

This study develops a simple, cost-effective and sensitive high-performance liquid chromatography with diode array detector (HPLC-DAD) method for the simultaneous determination of eight sulfonylurea herbicides (oxasulfuron, metsulfuron-methyl, triasulfuron, chlorsulfuron, amidosulfuron, mesosulfuron-methyl, bensulfuron-methyl and tritosulfuron) in rapeseed oil. Extraction of target analytes was performed using quick, easy, cheap, effective, rugged and safe-based procedure followed by solid-phase extraction (SPE) and dispersive solid-phase extraction (d-SPE) cleanup, and presents good performance for all of the analytes with recoveries in the range of 67-133% and relative standard deviations (RSD) less than 15%. No significant matrix interference was observed due to the application of effective zirconium dioxide-based sorbent (Z-Sep). Method LOQs for most of the investigated analytes were set at satisfactory low value of 20 ng g −1 in food product. The procedure was evaluated in analyses of actual samples. The most important steps of the method optimization are presented. Novel EMR-Lipid cleanup solution for samples with high fat content was evaluated and compared to Z-Sep sorbent.
