[Rapid determination of 129 pesticide residues in vegetables and fruits by gas chromatography-triple quadrupole mass spectrometry].
An analytical method for the simultaneous determination of 129 pesticides in vegetables and fruits was established based on optimized QuEChERS with gas chromatography-triple quadrupole mass spectrometry (GC-MS/MS). The samples were extracted with acetonitrile (containing 1% (v/v) acetic acid), then the extracts were determined by GC-MS/MS in multireaction monitoring (MRM) mode after being clean...
متن کاملRapid determination of fosetyl-aluminum residues in lettuce by liquid chromatography/electrospray tandem mass spectrometry.
This paper describes a new method for the sensitive and selective determination of fosetyl-aluminum (Al) residues in vegetable samples. The method involves extraction with water by using a high-speed blender and subsequent injection of the 5-fold diluted extract into the liquid chromatograph. Fosetyl-Al is determined by liquid chromatography with electrospray tandem mass spectrometry after the ...
متن کاملDetermination of tetracycline residues in soil by pressurized liquid extraction and liquid chromatography tandem mass spectrometry.
An optimized extraction and cleanup method for the analysis of chlortetracycline (CTC), doxycycline (DC), oxytetracycline (OTC) and tetracycline (TC) in soil is presented. Soil extraction in a pressurized liquid extraction system, followed by extract clean up using solid-phase extraction (SPE) and tetracycline determination by liquid chromatography tandem mass spectrometry (LC-MS/MS) provided a...
متن کاملPesticide residues analysis in Iranian fruits and vegetables by Gas Chromatography-Mass Spectrometry
Pesticide residues in fruits and vegetables are one of the highest concerns of consumers who need food safety. In this study, forty-eight pesticide residues from different chemical structure including organochlorine, organophosphorus, organonitrogen, dicarboximides, strobilurin, triazine, pyrethroids and other chemical groups. in 85 fruits and vegetables were determined and confirmed by GC-MS. ...
