Determination of cyantraniliprole and its major metabolite residues in vegetable and soil using ultra-performance liquid chromatography/tandem mass spectrometry.
A rapid, highly sensitive and selective method was developed for the determination of the cyantraniliprole and its major metabolite J9Z38 in cucumber, tomato and soil by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Target compounds were extracted with acetonitrile and an aliquot cleaned with primary and secondary amine. Two pairs of precursor product ion transi...
متن کاملNovel approach to fast determination of multiple pesticide residues using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
A rapid, high-throughput method employing ultra-performance liquid chromatography with tandem quadrupole mass spectrometry (UPLC-MS/MS) was developed and optimized for simultaneous quantification and confirmation of 64 pesticide residues and their toxic metabolites in fruit extracts prepared by a buffered QuEChERS procedure. The total time required for UPLC-MS/MS analysis was 8 min plus 2 min f...
متن کاملSimultaneous Analysis of Metabolite Residues from Degradation of Dithiocarbamates in Cereals Using Liquid Chromatography Coupled with Tandem Mass Spectrometry
Background and Objectives: Dithiocarbamates are groups of fungicides used to control pests of agricultural products. Analysis of these pesticides with liquid and gas chromatography instruments is associated with various problems due to the presence of metal groups in the structure of these compounds. Therefore, one of the ways for analysis the pesticides is to check the level of decomposition...
متن کاملValidation of the analysis method of 25 pesticide residues in rice using LC-MS/MS device (liquid chromatography-mass spectrometry)
Introduction: In recent years, due to the increase in the use of pesticides in agricultural products and its entry into the human food chain, there has been an increase in concerns about the health of food among people. Therefore, the purpose of conducting this research is to validate the analysis method. 25 pesticide residues in rice using LC-MS/MS. Methods: In this research, a simultaneous an...
متن کاملDetermination of the residues of 18 carbamate pesticides in chestnut and pine nut by GPC cleanup and UPLC-MS-MS.
A new method using gel permeation chromatography (GPC) cleanup followed by ultra-performance liquid chromatography combined with tandem mass spectrometry (UPLC-MS-MS) has been established for simultaneous determination of 18 carbamate pesticides in nuts (chestnut and pine nut). Recoveries obtained by fortifying nut (spiking at 0.02 mg/kg) range from 70.21% to 89.56%. The proposed method feature...
