[Simultaneous determination of dichlorvos, trichlorfon and naled in fruits and vegetables by liquid chromatography with tandem mass spectrometry].
A method for simultaneous determination of Dichlorvos (DDVP), Trichlorfon (DEP) and Naled (BRP) in fruits and vegetables by liquid chromatography with tandem mass spectrometry (LC/MS/MS) was developed. Pesticides were extracted with ethyl acetate together with phosphoric acid and anhydrous sodium sulfate, followed by an ENVI-Carb cartridge cleanup. Phosphoric acid prevented BRP from being conve...
متن کامل[Simultaneous determination of organophosphorus pesticides in cruciferous vegetables by dual-column GC with pulsed FPD and FTD].
We evaluated simultaneous analytical methods for organophosphorus pesticides in cruciferous vegetables by gas chromatography (GC). Firstly, 36 pesticides were selected on the basis of monitoring data (April 1996-March 2003) in Aichi Prefecture. A sample was extracted with acetonitrile and the acetonitrile layer was separated by salting-out. The extract was cleaned up with gel permeation chromat...
متن کامل[Simultaneous analysis of glyphosate and glufosinate in vegetables and fruits by GC-FPD].
A rapid analytical method for residues of the herbicide, glyphosate [N-(phosphonomethyl)glycine], glufosinate [DL-homoalanine-4-yl(methyl)phosphinic acid] and glufosinate metabolite (MPPA: 3-methylphosphinicopropionic acid) in vegetables and fruits was developed by improving the bulletin method of glufosinate. 50 mL of solution extracted with water (corresponding to 2 g of the sample) was loade...
متن کامل[Determination of diphenyl and o-phenylphenol in agricultural products by GC/MS].
A simple determination method of diphenyl (DP) and o-phenylphenol (OPP) in agricultural products by GC/MS was examined. DP and OPP were extracted with ethyl acetate in the presence of anh. sodium sulfate. After addition of n-butanol, the extract solution was concentrated. Clean-up was achieved by shaking with graphitized bulk carbon (Supelclean ENVI-Carb). Addition of polyethylene glycol sharpe...
متن کاملSimultaneous Determination of Trichlorfon and Dichlorvos Residues in Olive Flounder (Paralichthys olivaceus) by Liquid Chromatography-Mass Spectrometry: Validation and Application to Pharmacokinetics
Trichlorfon, an organophosphate insecticide, is used in aquaculture to control parasitic organisms. This study evaluated a rapid, sensitive, and specific LC-MS/MS method for the determination of trichlorfon and dichlorvos residues in the tissues of olive flounder. Separation was carried out on an Eclipse Plus C18 column by gradient elution using wateracetonitrile with 0.1% formic acid at a flow...
