“…Tandem mass spectrometers are the preferred method to develop efficient and fast quantitation from the same injection of multiple analytes in different product groups. [24,37] The UHPLC-MS/MS system consisted of a Thermo Accela UHPLC (pump, degasser, autosampler) coupled to a Thermo Quantum Access Max triple quadrupole mass spectrometer. An electro spray ionization (ESI) probe was used for atmospheric pressure ionization.…”

Lathyrus sativus L. is considered one of the most promising calorie and protein sources for the vast, expanding populations living in drought-prone and marginalized areas of the world. This study was conducted to determine the β-N-oxalyl-L-2,3-diaminopropionic acid (β-ODAP), L-homoarginine, and asparagine content of a total of 173 Lathyrus sativus L. genotypes, of which 93 were collected under natural conditions in Antalya. The β-ODAP, L-homoarginine, and asparagine content of Lathyrus sativus L. genotypes ranged from 1.55 to 20.8 mg/g seeds, 1.35 to 11.64 mg/g seeds, and 0.59 to 5.22 mg/g seeds, respectively.

“…the average recovery was in the range 70 -120 % with RSD ≤ 20 %), and was determined based on the accuracy and precision data obtained through the recovery studies. In this method, a single and quick step of extraction using ethyl acetate was used because it is equally acceptable for extraction of non-fatty food, and especially suitable for the extraction of high-sugar commodities like grapes, since sugar has limited solubility in ethyl acetate [13,14]. Furthermore, substitution of acetonitrile by ethyl acetate increased the recovery of OC, OP and SP and it substantially reduces the input cost of analysis (Figure 1).…”

The Quick Easy Cheap Effective Rugged and Safe (QuEChERS) multiresidue method has been validated for the extraction of 82 pesticides belonging to various chemical classes from grapes and pomegranate (commodities with high sugar and low lipid contents). A mixture of 82 pesticides amenable to gas chromatography (GC) was quantitatively recovered from spiked grapes and pomegranate and determined using gas chromatographytandem mass spectrometry (GC-MS/MS). The method employed involved initial extraction in a water/ethyl acetate system, an extraction/partitioning step after the addition of salt, and a cleanup step utilizing dispersive solid-phase extraction (d-SPE); this combination ensured that it was a rapid, simple and cost-effective procedure. The method setup is streamlined with the new software approach of Compound Based Scanning (CBS). The matrix-matched calibration results have demonstrated good reproducibility, robustness and linearity. The spiking levels for the recovery experiments were 0.005, 0.01 and 0.1 mg kg -1 for GC-MS/MS analyses. Adequate pesticide quantification and identity confirmation were attained, even at the lowest concentration levels, considering the high signal-to-noise ratios, the very good accuracies and precisions, as well as the good matches between the observed ion ratios. Mean recoveries mostly ranged between 70 and 110 % (91% on average), and RSD were generally below 12% (7.3% on average). The use of analyte protectants during GC analysis was demonstrated to provide a good alternative to the use of matrix-matched standards to minimize matrix-effect-related errors. For all compounds LODs were 0.001 to 0.005 mgkg -1 and LOQs were 0.005 to 0.020 mgkg -1. Correlation coefficients of the calibration curves were >0.991. Based on these results, the methodology has been proven to be highly efficient and robust and thus suitable for monitoring the Maximum Residual Limit (MRL) compliance of a wide range of commodity/pesticide combinations.

“…There have been some reports regarding the detection methods for organophosphorus pesticide residues, such as gas chromatography (GC) coupled with tandem mass spectrometry (Chen, Chen, Feng, & Li, 2009;Pang et al, 2006), GC with flame photometric detection (Dugo, Bella, Torre, & Saitta, 2005;Liu et al, 2014), GC with nitrogen-phosphorus detection (Shen, Su, Zhu, & Gao, 2007;Tian, Liu, Fang, An, & Duan, 2014), high performance liquid chromatography (He & Lee, 2006;Seebunrueng, Santaladchaiyakit, & Srijaranai, 2014), liquid chromatography coupled with tandem mass spectrometry (Ingelse, van Dam, Vreeken, Mol, & Steijger, 2001;Li et al, 2013;Mol, van Dam, & Steijger, 2003) , chemiluminescence (Chen, Lin, Cai, Chen, & Wang, 2008;Li, He, & Xu, 2007;Li, Hu, Huo, & Xu, 2006;Wang, Zhang, Wang, Yang, & Zhang, 2001), capillary electrophoresis-quantum dot/laser induced detection (CE-QD/LIF) (Chen & Fung, 2010) and biosensor (Sun & Wang, 2010). However, these methods require expensive instruments and lengthy analytical times.…”

In this study, a molecularly imprinted polymer that could selectively recognize trichlorfon was synthesized. Using the imprinted polymer as biomimetic antibody, a novel biomimetic immunoassay-capillary electrophoresis method with improved sensitivity was developed for the detection of trichlorfon. This method was based on the competitive reaction between quantum dot-labeled trichlorfon and free trichlorfon with the biomimetic antibody. Under optimal conditions, the limit of detection (IC 15 ) and the sensitivity (IC 50 ) of the method was 0.35 ± 0.021 μg/L and 0.81 ± 0.025 mg/L, respectively. To evaluate the accuracy of the method, trichlorfon spiked in the carrot and zucchini samples was determined, and the recovery was in the range of 80.1-95.3%. This method was also applied to the quantitative detection of trichlorfon residues in the edible rape and leek samples, and the results had a good correlation with those obtained using a gas chromatography method.
