Improvements in analytical methodology for the determination of frequently consumed illicit drugs in urban wastewater
(Springer, 2014-07)
Rapid and sensitive analytical methodology based on ultra high-performance liquid chromatography-tandem mass spectrometry has been developed for the determination of widely consumed drugs of abuse (amphetamines, MDMA, ...
Comprehensive analytical strategies based on high-resolution time-of-flight mass spectrometry to identify new psychoactive substances
(Elsevier, 2014-05)
In the past decade, an increasing number of new psychoactive substances (NPSs) were introduced on the drug markets through various modes of distribution, including the and smart shops. Recent reports on their adverse effects ...
Qualitative screening of 116 veterinary drugs in feed by liquid chromatography-high resolution mass spectrometry. Potential application to quantitative analysis
(Elsevier, 2014)
Veterinarian and human pharmaceuticals may be intentionally added to animal feed to enhance animal production. Monitoring these substances is necessary for protecting the consumers. In this work, a screening method covering ...
Validation of a qualitative screening method for pesticides in fruits and vegetables by gas chromatography quadrupole-time of flight mass spectrometry with atmospheric pressure chemical ionization
(Elsevier, 2014-08-01)
A wide-scope screening method was developed for the detection of pesticides in fruit and vegetables. The method was based on gas chromatography coupled to a hybrid quadrupole time-of-flight mass spectrometer with an ...
Improving Target and Suspect Screening High-Resolution Mass Spectrometry Workflows in Environmental Analysis by Ion Mobility Separation
(American Chemical Society, 2020-11-19)
Currently, the most powerful approach to monitor
organic micropollutants (OMPs) in environmental samples is the
combination of target, suspect, and nontarget screening strategies
using high-resolution mass spectrometry ...
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 ...
Monitoring a large number of pesticides and transformation products in water samples from Spain and Italy
(Elsevier, 2017-07)
Assessing the presence of pesticides in environmental waters is particularly challenging because of the huge number of substances used which may end up in the environment. Furthermore, the occurrence of pesticide transformation ...
Told through the wine: A liquid chromatography–mass spectrometry interplatform comparison reveals the influence of the global approach on the final annotated metabolites in non-targeted metabolomics
(Elsevier, 2016)
This work focuses on the influence of the selected LC-HRMS platform on the final annotated compounds in non-targeted metabolomics. Two platforms that differed in columns, mobile phases, gradients, chromatographs, mass ...
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 ...
The relevant role of ion mobility separation in LC-HRMS based screening strategies for contaminants of emerging concern in the aquatic environment
(Elsevier, 2021-05-05)
Ion mobility separation (IMS) coupled to high resolution mass spectrometry (IMS-HRMS) is a promising technique for (non-)target/suspect analysis of micropollutants in complex matrices. IMS separates ionized compounds based ...
