Determination of six microcystins and nodularin in surface and drinking waters by on-line solid phase extraction–ultra high pressure liquid chromatography tandem mass spectrometry
(Elsevier, 2012)
Microcystins and nodularin are cyclic peptides hepatotoxins produced by cyanobacterial genera (blue-green algae). Toxic cyanobacterial blooms are a worldwide problem, as reported in several countries, like China, Australia, ...
Occurrence and removal of pharmaceuticals in wastewater treatment plants at the Spanish Mediterranean area of Valencia
(Elsevier, 2012-04)
A survey on the presence of pharmaceuticals in urban wastewater of a Spanish Mediterranean area (Castellon province) was carried out. The scope of the study included a wide variety of pharmaceuticals belonging to different ...
Simultaneous determination of triazines and their main transformation products in surface and urban wastewater by ultra-high-pressure liquid chromatography- tandem mass spectrometry
(Springer Verlag, 2010)
This work describes the optimization, validation and application to real samples of an ultra-high-pressure liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for the quantification and confirmation of 11 ...
In-depth comparison of the metabolic and pharmacokinetic behaviour of the structurally related synthetic cannabinoids AMB-FUBINACA and AMB-CHMICA in rats
(Springer Nature, 2022-02-24)
Synthetic cannabinoids receptor agonists (SCRAs) are often almost completely metabolised, and hence their pharmacokinetics should be carefully evaluated for determining the most adequate biomarker in toxicological analysis. ...
Fragmentation pathways of drugs of abuse and their metabolites based on QTOF MS/MS and MSE accurate-mass spectra
(John Wiley, 2011-09)
A study of the fragmentation pathways of several classes of drugs of abuse (cannabinoids, ketamine, amphetamine and amphetamine-type stimulants (ATS), cocaine and opiates) and their related substances has been made. The ...
Benefits of Collision Cross Section (CCS) data obtained by UPLC-ESI-IMS-QTOF MS and GC-APGC-IMS-QTOF for small molecules identification in screening applications
(Sociedad Española de Cromatografía y Técnicas Afines, 2022)
The coupling ion mobility separation to high-resolution
mass spectrometry (IMS-HRMS) techniques, usually hyphenated with liquid or gas chromatography (LC/GC),
are advanced tools for wide-scope screening for a
large ...
Multi-class determination of personal care products and pharmaceuticals in environmental and wastewater samples by ultra-high performance liquid-chromatography-tandem mass spectrometry
(Elsevier, 2012-09)
In this work, a multi-class method for the simultaneous determination of 17 emerging contaminants, including pharmaceuticals and personal care products, has been developed. Target analytes were two anti-inflammatories, a ...
Electrochemical oxidation of dibenzothiophene compounds on BDD electrode in acetonitrile–water medium
(Elsevier, 2019-05-23)
The electrochemical oxidation of dibenzothiophene and two derivatives, namely 4-methyldibenzothiophene and 4,6-dimethyldibenzothiophene, was investigated either separately or as a mixture, on a BDD anode in a miscible ...
Study of cyanotoxin degradation and evaluation of their transformation products in surface waters by LC-QTOF MS
(Elsevier, 2019-08)
In the present work, the degradation of three cyanotoxins from the hepatotoxins group was investigated under laboratory-controlled experiments in water samples. Surface waters spiked with microcystin-LR (MC-LR), nodularin ...
Investigation of degradation products of cocaine and benzoylecgonine in the aquatic environment
(Elsevier, 2013-01)
In this work, ultra-high-performance liquid chromatography (UHPLC) coupled to a hybrid quadrupole time-of-flight mass spectrometer (QTOF MS) has allowed the discovery and elucidation of degradation products of cocaine and ...
