Determination of 17b-estradiol and 17a-ethinylestradiol in water at sub-ppt levels by liquid chromatography coupled to tandem mass spectrometry
(Royal Society of Chemistry, 2014-06)
Steroid estrogens are a group of endocrine disrupting compounds (EDCs) excreted in human urine mainly as glucuronide or sulfate conjugates, which might be converted back into the free estrogens in water. The natural estrogen ...
Screening of Pharmaceuticals and Illicit Drugs in Wastewater and Surface Waters of Spain and Italy by High Resolution Mass Spectrometry using UHPLC-QTOF MS and LC-LTQ-Orbitrap MS
(Springer, 2015)
The existence of pharmaceuticals and illicit drugs (PIDs) in environmental waters has led many analytical chemists to develop screening methods for monitoring purposes. Water samples can contain a huge number of possible ...
Novel analytical approach for brominated flame retardants based on the use of gas chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry with emphasis in highly brominated congeners
(American Chemical Society, 2015)
The analysis of brominated flame retardants (BFRs) commonly relies on the use of gas chromatography coupled to mass spectrometry (GC-MS) operating in electron ionization (El) and electron capture negative ionization (ECNI) ...
Analytical strategy to investigate 3,4-methylenedioxypyrovalerone (MDPV) metabolites in consumers’ urine by high-resolution mass spectrometry
(Springer, 2016-01)
The potential of high-resolution mass spectrometry (HRMS) for the investigation of human in vivo metabolism of 3,4-methylenedioxypyrovalerone (MDPV) using urine collected from a consumer (this is, in non-controlled ...
Assessing alcohol consumption through wastewater-based epidemiology: Spain as case study
(Elsevier, 2020-08-19)
Background
In this study, an alternative and complementary method to those approaches currently used to estimate alcohol consumption by the population is described. This method, known as wastewater-based epidemiology ...

Untargeted Metabolomics in Doping Control: Detection of New Markers of Testosterone Misuse by Ultrahigh Performance Liquid Chromatography Coupled to High-Resolution Mass Spectrometry
(American Chemical Society, 2015)
The use of untargeted metabolomics for the
discovery of markers is a promising and virtually unexplored
tool in the doping control field. Hybrid quadrupole time-of-
flight (QTOF) and hybrid quadrupole Orbitrap (Q ...
Investigation of pharmaceuticals and illicit drugs in waters by liquid chromatography-high-resolution mass spectrometry
(Elsevier, 2014)
Mass spectrometry (MS) coupled to chromatography has been increasingly used in the environmental field, as it allows the best performance currently attainable for the investigation of a wide range of organic pollutants. ...
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 ...
