Bicyclic naphthenic acids in oil sands process water: Identification by comprehensive multidimensional gas chromatography–mass spectrometry

Authors: Michael J. Wilde, Charles E. West, Alan G. Scarlett, David Jones, Richard A. Frank, L. Mark Hewitt, Steven J. Rowland Abstract Although bicyclic acids have been reported to be the major naphthenic acids in oil sands process-affected water (OSPW) and a well-accepted screening assay indicated that some bicyclics were the most acutely toxic acids …

Gas phase dehydration of lactic acid to acrylic acid over alkaline-earth phosphates catalysts

Authors: E. Blanco, P. Delichere, J.M.M. Millet, S. Loridant Abstract A series of alkaline-earth phosphates were prepared by co-precipitation method using sodium free or sodium containing precursors and evaluated for gas phase dehydration of lactic acid. The catalysts were characterized by BET measurements, X-ray diffraction, chemical analysis, XPS spectroscopy and both NH3 and CO2-TPD. After checking …

Different headspace solid phase microextraction – Gas chromatography/mass spectrometry approaches to haloanisoles analysis in wine

Authors: Henryk H. Jeleń, Mariusz Dziadas, Małgorzata Majcher Abstract Three approaches in determination of six haloanisoles (2,4,6-trichloroanisole, 2,3,4-trichloroanisole, 2,3,6-trichloroanisole, tetrachloroanisole, pentachloroanisole and 2,4,6-tribromoanisole) in wine were compared. Comprehensive gas chromatography – time of flight mass spectrometry (GC × GC–ToF-MS) was described for the first time for this application and compared to gas chromatography–tandem mass spectrometry (GC–MS/MS) using …
