“…Table 1 shows examples of sorbents and salts used in the purification stage. The most frequently used compounds were PSA (primary secondary amine), octadecyl sorbent C18, SAX (quaternary amine), Z-Sep (sorbent based on modified silica gel with oxide zirconium) and GCB (graphitized carbon black) [ 16 , 17 , 20 , 25 , 30 ]. These are sorbents that are responsible for the removal of polar organic acids, some sugars, lipids and sterols, carotenoids and chlorophyll [ 44 ].…”

“…Moreover, the analytical method developed was linked with other gas (GC) and liquid chromatography (LC) methods reported in the literature for pesticide quantification in vegetables, Table 4 [1,3,5,8,12,16,[31][32][33][34][35]. The sample amount (g), LOD, LOQ and recovery (analytical performance) were considered to demonstrate the advantages of the QuEChERS-dSPE/UHPLC-PDA method here validated.…”

“…The analysis of insecticide residues in foods requires highly selective and sensitive analytical methods. Current analytical methods include mass spectrometry (MS) or tandem mass spectrometry (MS/MS) detection, coupled to gas (GC) or liquid chromatography (LC) [4,8,16]. Nevertheless, ultra-high-performance chromatography (UHPLC) can be a fascinating substitute in the analysis of insecticide residues, due to its great resolution, reduced analysis time, lower solvent volumes and improved selectivity [17].…”

“…In 2018, Fernande et al [ 110 ] used modified QuEChERS to analyze organophosphorus pesticides in strawberries with recovery values of 72–115%, limit of detection (LOD) and limit of quantification (LOQ) values ranging 3.64–10.38 µg/kg recorded. Similarly, the modified QuEChERS method for analyzing organophosphate pesticides in fruits and vegetables and recovery values in the range of 76.89–110.3 µg/kg, together with LOD and LOQ values from 0.1–1.0 µg/kg and 0.5–5 µg/kg, respectively, were reported [ 111 ]. More detailed reviews on QuEChERS, and its use on the analysis of various pollutants in various food commodities, have been reported in the literature [ 107 , 108 , 109 ].…”
