Analytical strategy based on the use of liquid chromatography and gas chromatography with triple-quadrupole and time-of-flight MS analyzers for investigating organic contaminants in wastewater
Springer Verlag (2010)The presence of a wide variety of organic pollutants with different physico-chemical characteristics has been investigated in wastewater samples from a municipal solid waste treatment plant placed at Castellón, Spain. An ... -
Determination of patulin in apple and derived products by UHPLC-MS/MS. Study of matrix effects with atmospheric pressure ionisation sources.
Elsevier (2014)Sensitive and reliable analytical methodology has been developed for the measurement of patulin in regulated foodstuffs by using ultra-high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC–MS/MS) ... -
Liquid chromatography coupled to tandem mass spectrometry for the residue determination of ethylenethiourea (ETU) and propylenethiourea (PTU) in water
Elsevier (2012)Ethylenethiourea (ETU) and propylenethiourea (PTU) are the main degradation products of dithiocarbamates fungicides, which are widely used in agriculture from several years ago. Their determination in water at low ... -
Quantification, confirmation and screening capability of UHPLC coupled to triple quadrupole and hybrid quadrupole time-of-flight mass spectrometry in pesticide residue analysis
John Wiley & Sons (2010-04)The potential of three mass spectrometry (MS) analyzers (triple quadrupole, QqQ; time of flight, TOF; and quadrupole time of flight, QTOF) has been investigated and compared for quantification, confirmation and screening ... -
Tècniques metabolomiques per a la discriminació d’olis d’oliva verge extra per origen amb Cromatografia de Líquids d’Ultra Alta Ressolució acoblada a Espectrometría de Masses Quadrupol-Temps de vol
Universitat Jaume I (2014-06-27)La metabolòmica ha proporcionat a la comunitat científica una ferramenta que ha demostrat perfectament la seva capacitat de proporcionar informació sobre matrius extremadament complexes com el metabolisme humà, o qualsevol ... -
The classification of almonds (Prunus dulcis) by country and variety using UHPLC-HRMS-based untargeted metabolomics
Taylor & Francis (2018-01-17)The aim of this study was to use an untargeted UHPLC-HRMS-based metabolomics approach allowing discrimination between almonds based on their origin and variety. Samples were homogenised, extracted with ACN:H2O (80:20) ... -
