Optimization and validation of a quantitative liquid chromatography–tandem mass spectrometric method covering 295 bacterial and fungal metabolites including all regulated mycotoxins in four model food matrices
(2015-06-10)
An LC–MS/MS “dilute and shoot” method for the determination of 295 fungal and bacterial metabolites was optimized and validated according to the guidelines established in the Directorate General for Health and Consumer ...
A Standardized Index for Assessing Seawater Intrusion in Coastal Aquifers: The SITE Index
(Springer, 2016)
A large number of coastal aquifers worldwide are impacted by seawater intrusion. A
major aim of European Directives 2000/60/EC and 2006/118/EC is to achieve good ecological
status in groundwater bodies, including coastal ...
A methodology to analyse and assess pumping management strategies in coastal aquifers to avoid degradation due to seawater intrusion problems
(Springer, 2016)
In this paper we will focus on an interesting and complex problem, the analysis of
coastal aquifer management alternatives in aquifers affected by seawater intrusion problems. A
systhematic method based on an approximation ...

(ACS Publications, 2020-06-12)
Severe acute respiratory syndrome coronavirus 2 (SARSCoV-2), a novel member of the Coronaviridae family, has been identified as the etiologic agent of an ongoing pandemic
of severe pneumonia known as COVID-19.1 To date ...
Building an empirical mass spectra library for screening of organic pollutants by ultra-high-pressure liquid chromatography/hybrid quadrupole time-of-flight mass spectrometry
(John Wiley, 2011-01-30)
Hybrid quadrupole time-of-flight mass spectrometry (QTOF MS) has gained wide acceptance in many fields of chemistry, for example, proteomics, metabolomics and small molecule analysis. This has been due to the numerous ...
Untargeted metabolomics approach for unraveling robust biomarkers of nutritional status in fasted gilthead sea bream (Sparus aurata)
(PeerJ, 2017)
A metabolomic study has been performed to identify sensitive and robust biomarkers
of malnutrition in farmed fish, using gilthead sea bream (Sparus aurata) as a model.
The metabolomic fingerprinting of serum from fasted ...
Evaluation of uncertainty sources in the determination of testosterone in urine by calibration-based and isotope dilution quantification using ultra high performance liquid chromatography tandem mass spectrometry
(Elsevier, 2017-06)
Three quantification methodologies, namely calibration with internal standard (Cal-IS, non-weighted), weighted calibration with internal standard (wCal-IS) and isotope pattern deconvolution (IPD) have been used for the ...
Development of a Retention Time Interpolation scale (RTi) for liquid chromatography coupled to mass spectrometry in both positive and negative ionization modes
(Elsevier, 2018-07)
The accuracy and sensitivity of high resolution mass spectrometry (HRMS) enables the identification of candidate compounds with the use of mass spectrometric databases among other tools. However, retention time (RT) data ...
Simultaneous determination of dechloranes, polybrominated diphenyl ethers and novel brominated flame retardants in food and serum
(Springer Verlag, 2017)
A sensitive method for the simultaneous quantification of dechloranes, polybrominated diphenyl ethers (PBDEs) and novel brominated flame retardants (NBFRs) has been developed for gas chromatography (GC) coupled to tandem ...
First nation-wide estimation of tobacco consumption in Spain using wastewater-based epidemiology
(Elsevier, 2020-11-01)
Wastewater-based epidemiology (WBE) has become a very useful tool to monitor a
population’s drug consumption or exposure to environmental and food contaminants. In this
work, WBE has been applied to estimate tobacco ...
