Gas chromatography-mass spectrometry determination of polybrominated

Gas chromatography coupled to mass spectrometry in negative chemical ionization (NCI) 11 mode has been applied to the quantification and reliable identification of polybrominated 12 diphenyl ethers (PBDEs) in animal and vegetable samples from aquaculture activities. 13 Matrices analyzed included fish fillet, fish feed, fish oil and linseed oil, which their fat content 14 ranged from 5 to 100%. ...

Perchloroethylene Analysis by Chemical Oxidation and Determination of Intermediate Products by Gas Chromatography, Mass Spectrometry

Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...

Determination of 3'-phosphoadenosine-5'- phosphosulfate in cells using hydrophilic interaction liquid chromatography and mass spectrometry

Determination of residual clopidol in chicken muscle by capillary gas chromatography-negative chemical ionization-mass spectrometry.

A selective, sensitive gas chromatography-mass spectrometry (GC-MS) method with negative chemical ionization (NCI) was developed for the detection and quantification of clopidol in chicken muscle. Chicken muscle samples were extracted with acetonitrile and concentrated to dryness; the residue was redissolved in ethyl acetate and applied to an Alumina B cartridge for cleanup. The residue was der...
