New insights into the search of meat quality biomarkers assisted by Orbitrap Tribrid untargeted metabolite analysis and chemometrics
(Elsevier, 2023)
Metabolite profiles of normal and defective dry, firm and dark (DFD) meat extracts with known ultimate pH
(pHu) values were determined by Orbitrap Tribrid ID-X untargeted analysis coupled to chemometrics. An
intelligent ...
Proposal of 5-methoxy-N-methyl-N-isopropyltryptamine consumption biomarkers through identification of in vivo metabolites from mice
(Elsevier, 2017-07)
New psychoactive substances (NPS) are a new breed of synthetically produced substances designed to mimic the effects of traditional illegal drugs. Synthetic cannabinoids and synthetic cathinones are the two most common ...
Use of soft and hard ionization techniques for elucidation of unknown compounds by gas chromatography/time-of-flight mass spectrometry
(John Wiley, 2011-05-11)
Investigation of trace-level non-target compounds by gas chromatography/mass spectrometry (GC/MS) often is a challenging task that requires powerful software tools to detect the unknown components, to obtain the deconvoluted ...
Behaviour of emerging contaminants in sewage sludge after anaerobic digestion
(Elsevier, 2016)
Nowadays, there is an increasing concern over the presence of contaminants in the aquatic environment, where they can be introduced from wastewater after their incomplete removal in the treatment plants. In this work, ...
The NORMAN Suspect List Exchange (NORMAN-SLE): facilitating European and worldwide collaboration on suspect screening in high resolution mass spectrometry
(Springer, 2022-10-21)
Background
The NORMAN Association (https://www.norman-network.com/) initiated the NORMAN Suspect List Exchange (NORMAN-SLE; https://www.norman-network.com/nds/SLE/) in 2015, following the NORMAN collaborative trial on ...
Analysis of polychlorinated dibenzo-p-dioxins and dibenzofurans in stack gas emissions by gas chromatography-atmospheric pressure chemical ionization-triple-quadrupole mass spectrometry
(Elsevier, 2017-09)
A gas chromatography coupled to triple-quadrupole mass spectrometry (GC-(QqQ)MS/MS) including a soft-ionization through an atmospheric pressure chemical ionization (APCI) source based method was compared with the high ...
Analytical methodologies based on LC–MS/MS for monitoring selected emerging compounds in liquid and solid phases of the sewage sludge
(Elsevier, 2016)
In this work, two analytical methodologies based on liquid chromatography coupled to tandem mass
spectrometry (LC–MS/MS) were developed for quantification of emerging pollutants identified in sewage sludge
after a previous ...
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 ...
Novel sampling strategy for alive animal volatolome extraction combined with GC-MS based untargeted metabolomics: Identifying mouse pup pheromones
(Elsevier, 2021-08-04)
In this study, we identify 11 mouse pup volatiles putatively involved in maternal care induction in adult females. For this purpose, we have adapted the dynamic headspace methodology to extract the volatolome of whole alive ...
