“…Apart from the MWCNTs, the m-PFC nanotubes were packed with PSA, GCB, or MgSO 4 , which greatly improved the purification efficiencies. Previous literature reports showed that the m-PFC method had outstanding purification abilities in complex samples, such as vegetables, fruits, and lipids [19,20]. In this study, two kinds of m-PFC columns were investigated, including NANO-C and NANO-V. NANO-V was composed of MWCNTs and MgSO 4 , and NANO-C was a mixture of PSA, GCB, MWCNTs, and MgSO 4 .…”

“…At present, the d-SPE-based QuECh-ERS method has gained great popularity among researchers for analyzing pesticide residues in fruits [12][13][14], vegetables [12][13][14], cereals [12,15], and other matrices [16,17]. In addition, there arose another novel cleanup method, the multiplug filtration cleanup (m-PFC) method, which is based on multiwalled carbon nanotubes (MWCNTs), and is effective in removing interferences [16,18,19]. The m-PFC materials were designed based on MWCNTs mixed with primarysecondary amines (PSA) and graphitized carbon black (GCB).…”

The detection frequencies of tefuryltrione, a new type of 4-hydroxyphenyl-pyruvate dioxygenase inhibitor herbicide, are rarely reported, probably because of the paucity of analytical methods. Herein, an effective and sensitive analytical method has been developed to detect tefuryltrione in vegetables (tomato and cucumber), cereals (rice and corn), soil, and water by ultra high performance liquid chromatography coupled with tandem mass spectrometry. Comparisons of the performances of dispersive solid-phase extraction and multiplug filtration cleanup methods were carried out for tefuryltrione in complex matrices. Extraction solvents and purification sorbents were further optimized for dispersive solid-phase extraction. Tefuryltrione was analyzed with electrospray ionization in the positive mode within 2.0 min. Mean recoveries for tefuryltrione were 75.4-108.9% with relative standard deviations less than 11.0% at three fortification levels (10, 100, 500 μg/kg) in the sample matrixes. Limits of quantification ranged from 0.70 to 5.12 μg/kg, and an excellent linearity (R ≥ 0.9902) was obtained for tefuryltrione at concentrations of 5-1000 μg/L. The results showed that the developed dispersive solid-phase extraction method could serve as an effective, sensitive, and robust method for routine monitoring of tefuryltrione residue in plants and environmental samples.

A rapid and effective method was developed for the analysis of 39 pesticide residues in porcine meat with dual-layer multiplug filtration cleanup and gas chromatographytandem mass spectrometry detection. The cleanup process was performed with columns packed with two layers, namely multiwalled carbon nanotubes, C18 and anhydrous magnesium sulfate (MgSO 4 ) as top layer, while mixture of florisil and MgSO 4 as bottom layer. A single-layer method was tested in parallel, with columns packed with the same amount of absorbents. Extraction conditions and filtration cleanup process were optimized to obtain satisfied method performance. Method linearity was calculated with coefficients of determination more than 0.995. The limits of quantitation were verified with acceptable accuracy at the lowest spiked concentration of 0.01 mg/kg (except pyrimethanil). The recoveries at three fortified levels (0.01, 0.05, and 0.1 mg/kg) in five replicates were between 74 and 118% (except pyrimethanil) with relative standard deviations range from 1 to 16%. The matrix effects were in the range of 1.01 to 2.84. This new method was applied for the analysis of multipesticide residues in market samples of porcine meat. This study showed the dual-layer multiplug filtration cleanup demonstrated better performance than that with the single-layer columns in cleanup of porcine meat.

“…In our previous studies, we focused on optimizing the times of pull and push of m-PFC column. [23][24][25] In this study, an automated multi-channel multiplug ltration cleanup device was developed, which could improve the efficiency and precision and avoid the error causing by manual operation. In order to evaluate the automated device, the recoveries of 82 pesticides in mulberry leaf and mulberry processed tea were investigated under different parameters.…”
