Multi-walled carbon nanotubes as alternative reversed-dispersive solid phase extraction materials in pesticide multi-residue analysis with QuEChERS method.
A multi-residue method based on modified QuEChERS sample preparation with multi-walled carbon nanotubes (MWCNTs) as reversed-dispersive solid phase extraction (r-DSPE) material and gas chromatography-mass spectrometry determination by selected ion monitoring (GC/MS-SIM) mode was validated on 30 representative pesticides residues in vegetables and fruits. The acetonitrile-based QuEChERS (quick, ...
متن کاملAutomated Sample Preparation and Analysis Workflows for Pesticide Residue Screening in Food Samples using DPX- QuEChERS with LC-MS/MS
QuEChERS (quick, easy, cheap, effective, rugged, and safe) sample preparation methods have been developed to help monitor pesticides in a range of food samples. These methods require many manual steps, such as shaking, centrifugation, and dispersive SPE cleanup, making it a quite labor-intensive process. There is a need for automating parts of QuEChERS extraction in order to improve laboratory ...
متن کاملA Modified Multi-residue Method for Analysis of 150 Pesticide Residues in Green Beans Using Liquid Chromatography-tandem Mass Spectrometry
Three methods of sample preparation and analysis of 150 pesticides in green beans were evaluated by LCMS/MS detection. The mass spectrometry parameters were optimized to give the best sensitivity, and two multiple reaction monitoring modes (MRMs) were chosen for quantification and conformation, based on the optimized declustering potential and collision energy. The first Quick, easy, cheap, eff...
متن کاملEvaluation of the QuEChERS sample preparation approach for the analysis of pesticide residues in olives.
This paper describes the use of a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for extraction and cleanup of 16 pesticide residues of interest in olives and olive oil. These products contain a high lipid content, which can adversely affect pesticide recoveries and harm traditional chromatographic systems. For extraction, the main factors (oil and water content) were studied...
متن کاملComparison of QuEChERS sample preparation methods for the analysis of pesticide residues in fruits and vegetables.
This article describes the comparison of different versions of an easy, rapid and low-cost sample preparation approach for the determination of pesticide residues in fruits and vegetables by concurrent use of gas and liquid chromatography (GC and LC) coupled to mass spectrometry (MS) for detection. The sample preparation approach is known as QuEChERS, which stands for "quick, easy, cheap, effec...
