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...

Gas Chromatography-Mass Spectrometry

Gas chromatography (GC) is a widely applied technique in many branches of science and technology. For over half a century, GC has played a fundamental role in determining how many components and in what proportion they exist in a mixture. However, the ability to establish the nature and chemical structure of these separated and quantified compounds is ambiguous and reduced, and requires a spect...
