Comparison of experimental methods for measuring infinite dilution volatilities of aroma compounds in water/ethanol mixtures
(AMER CHEMICAL SOC, 2004)
Several experimental methodologies exist for measuring volatilities; however, results show great dispersion and sometimes lack of agreement between different methods. The aim of our study was to compare the performance of ...
Evaluation of Headspace Solid-Phase Microextraction Gas Chromatography–Mass Spectrometry for the Characterization of Volatile Organic Compounds from Melon (Cucumis melo L.) Flowers
(2018-08-01)
Abstract: The secondary metabolism of plants plays a key role in plant–insect interactions. Among the various classes of metabolites produced, volatile organic compounds (VOCs) play important echophysiological roles, ...
Development of an analyser to determine the oxygen and carbon dioxide levels in the head-space of packages

Headspace-mass spectrometry with alternative chromatographic separation using a column switching system for the screening and determination of BTEX and styrene in comestible oil
(Taylor & Francis, 2010-01)
A headspace-mass spectrometry with alternative chromatographic separation using a column switching system was developed for the screening and confirmation of BTEX and styrene in comestible oils. According to the position ...
Determination of volatile organic compounds in recycled polyethylene terephthalate and high-density polyethylene by headspace solid phase microextraction gas chromatography mass spectrometry to evaluate the efficiency of recycling processes
(ELSEVIER SCIENCE BV, 2011)
A method for the determination of volatile organic compounds (VOCs) in recycled polyethylene terephthalate and high-density polyethylene using headspace sampling by solid-phase microextraction and gas chromatography coupled ...
Determination of eight fatty acid ethyl esters in meconium samples by headspace solid-phase microextraction and gas chromatography-mass spectrometry
(WILEY-V C H VERLAG GMBH, 2010)
A number of fatty acid ethyl esters (FAEEs) have recently been detected in meconium samples. Several of these FAEEs have been evaluated as possible biomarkers for in utero ethanol exposure. In the present study, a method ...
Study of methods for the extraction of volatile compounds from fermented grape must
(Elsevier Sci LtdOxfordInglaterra, 2006)
Validation of a manual headspace gas chromatography method for determining volatile compounds in biological fluids
(AMER SOC CLINICAL PATHOLOGY, 2008)
Background: We report the validation of a method for the determination of acetaldehyde, acetone, methanol, and ethanol in biological fluids using manual headspace sample introduction and an acetonitrile internal standard. ...
