“…Standardized analytical techniques such as gas and liquid chromatography are well-established for the quantification of TFs in real samples [10,11]. While these analytical instruments offer good selectivity and sensitivity for the simple or very low matrix samples, they may encounter challenges regarding selectivity and matrix effect, when dealing with very complex samples.…”

Solvent‐assisted dispersive solid‐phase extraction (SA‐DSPE) approach was developed to measure triazole fungicides (TFs). In the SA‐DSPE technique, the addition of 1000 μL of ethanol as a disperser solvent, along with a small quantity of benzil as a sorbent to the sample solution, led to a cloudy solution. After completion of the extraction, the mixture was subjected to centrifugation to isolate benzil. Next, benzil was dissolved in ethanol, and the resulting solution was subsequently analyzed by a gas chromatography‐flame ionization detector. This method demonstrated high linearity (R2 > 0.9963) and repeatability (relative standard deviation % < 4.3) for the quantification of TFs under the optimal conditions (sorbent: benzil, amount of benzil: 2% w/v, pH of solution: 7.0, disperser solvent: ethanol, volumes of ethanol: 1000 μL, centrifuge time: 3 min, extraction temperature: 25°C, and ionic strength: without salt addition). The proposed SA‐DSPE yielded detection limits, quantification limits, and preconcentration factors within the ranges of 0.3–0.9 ng/mL, 1.0–3.0 ng/mL, and 419–426, respectively. Finally, the validated method was employed to determine TFs in a diverse range of real samples, encompassing waters, fruits, vegetables, and agricultural soils, with relative recoveries ranging from 93.0% to 104%.

“…With the development of chromatographic column technology and high-efficiency separation equipment, reversed-phase liquid chromatography (RPLC) and SFC have provided great advantages in the separation of stereoisomers. Previous studies have demonstrated the applicability of RPLC and SFC for the analysis of pesticides in fruits, vegetables, and soil, especially for chiral separations of stereoisomers [15][16][17][18][19][20][21][22][23]. As a novel analytical technique SFC has attracted increasing attention among researchers.…”

This study used reversed‐phase liquid chromatography–tandem mass spectrometry and supercritical fluid chromatography–tandem mass spectrometry for determination of the stereoisomers of chlorfenvinphos and dimethylvinphos in tobacco. Tobacco samples were extracted and purified with a modified quick, easy, cheap, effective, rugged, and safe technique using spherical carbon. The performance of both methodologies was comprehensively compared in terms of methods validation parameters (separation efficiency, linearity, selectivity, recovery, repeatability, sensitivity, matrix effect, etc.). Under optimized conditions, the calibration curves of the stereoisomers of chlorfenvinphos and dimethylvinphos in the range of 10–500 ng/mL showed excellent linearity with R2 ≥ 0.997 in both methods. The adequate recoveries of analytes from three different spiked tobaccos were obtained using reversed‐phase liquid chromatography–tandem mass spectrometry (86.1–95.7%) as well as supercritical fluid chromatography–tandem mass spectrometry (86.5–94.0%). The relative standard deviations for spiked samples were all below 7.0%. Compared with supercritical fluid chromatography–tandem mass spectrometry, lower matrix effects and LODs can be obtained in reversed‐phase liquid chromatography–tandem mass spectrometry.

“…6 Triazole fungicides possess a chiral center comprising one or two pairs of enantiomers that exhibit identical physicochemical properties. 7 However, the enantiomers differ signicantly in terms of their biological activity, toxicity, metabolism, excretion, distribution, and bioaccumulation. 5 TF consists of one chiral center and two enantiomers S-TF and R-TF.…”
