文献和实验We have developed a method using in-tube solid-phase microextraction coupled with liquid chromatography-mass spectrometry (SPME-LC-MS) for the assay of herbicides in water samples. Chlorinated phenoxy acid herbicides have been automatically
Quick, Easy, Cheap, Effective, Rugged, and Safe Approach for Determining Pesticide Residues
by a simple cleanup step known as dispersive solid-phase extraction (dispersive-SPE). The QuEChERS method is carried out by shaking a fluoroethylenepropylene (FEP) centrifuge tube that contains 1 mL 1% HAc in MeCN plus 0.4 g anhydrous MgSO4 and 0.1 g anhydrous
QuEChERS Sample Preparation Approach for Mass Spectrometric Analysis of Pesticide Residues in Foods
This chapter describes an easy, rapid, and low-cost sample preparation approach for the determination of pesticide residues in foods using gas and/or liquid chromatographic (GC and/or LC) analytical separation and mass spectrometric
