“…In this study, the matrix effects of m-PFC and d-SPE method were compared by the slope ratio of matrix-matched and solvent standards. Generally, the matrix effect can be ignored for values in the range of 0.9-1.1 (Wu et al 2020). The ME is considered to be weakened when it is less than 0.9, and enhanced when it is gteater than 1.1.…”

For minor crops such as jasmine, the lack of pesticide registration and maximum residue limits are important issues that need to be solved in order to facilitate trading and ensure food safety. Meanwhile, reliable and quick analytical methods for multi-pesticide residues in these commodities are few, but required by various stakeholders. In this study, a method for detecting 25 of the most frequently used pesticides in jasmine ower and its scented tea by multi-plug ltration cleanup and ultra-high-performance liquid chromatography-tandem mass spectrometry was developed and validated. The cleanup process was optimized and compared with the dispersive solid phase extraction procedure. Results showed that the relative standard deviations of multi-plug ltration cleanup method in precision tests were smaller. The absence of any solvent evaporation, vortices and additional centrifugation processes made this approach more rapid. The method was validated, showing that except for methomyl, recoveries of 25 pesticides were 64-108%, with relative standard deviations (n = 5) of 0.33-10%. The method was successfully applied to detect pesticide residues in marketed jasmine ower and scented tea samples. The results showed that some samples contained a combination of different residues, with neonicotinoids, organophosphates and pyrethroids being the three main types detected in both ower and tea samples.

“…Furthermore, MWCNTs address the issue of adsorption of planar pesticides, improving upon the limitations observed with graphitized carbon black (GCB). [23][24][25][26][27][28] Han et al 29 established a pesticide residue analysis method for 124 pesticides in liquor, sorghum, and rice hulls by combining m-PFC with GC-MS/MS. Qin et al 30 established an m-PFC clean-up method for 25 pesticides in six typical matrices, including wheat, spinach, and carrot, and compared it with the QuEChERS method, which stands for quick, easy, cheap, effective, rugged, and safe.…”

“…By realizing one-step purification, the purification time is greatly shortened and the pretreatment efficiency can be greatly improved. It has been applied to the detection of multi-pesticide residues in ginseng, agricultural products, fruits and vegetables [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. The main detection methods are gas chromatography-mass spectrometry (GC-MS/MS) and liquid chromatography-mass spectrometry (LC-MS/MS) [ 19 , 29 , 30 , 31 , 32 , 33 ].…”

A new method for screening pesticide residues in vegetable and fruit juices by the multi-plug filtration cleanup (m-PFC) method combined with gas chromatography-electrostatic field orbitrap high resolution mass spectrometry(GC-Orbitrap/MS) was developed. The samples were extracted with acetonitrile, purified with m-PFC and determined by GC-Orbitrap/MS. Qualitative analysis was confirmed by retention time, accurate molecular mass and quantitative analysis were performed with the matrix standard calibration. It could eliminate matrix interference effectively. Eight kinds of typical samples (orange juice, apple juice, grape juice, strawberry juice, celery juice, carrot juice, cucumber juice, tomato juice) were evaluated. The linear ranges of the 350 pesticides were from 5 to 500 μg/kg, with good correlation coefficients greater than 0.990. The limits of detection (LODs) were 0.3–3.0 μg/kg and the limits of quantification (LOQs) were 1.0–10.0 μg/kg. The average recoveries at three spiked levels of 10, 100, 200 μg/kg were in the range of 72.8–122.4%, with relative standard deviations (RSDs) of 2.0–10.8%. The method has effectively improved the determination efficiency of pesticide residue screening by high-resolution mass spectrometry in vegetable and fruit juices.
