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 ... -
Comprehensive strategy for pesticide residue analysis through the production cycle of gilthead sea bream and Atlantic salmon
Elsevier (2017-07)Plant ingredients and processed animal proteins are alternative feedstuffs for fish feeds in aquaculture. However, their use can introduce contaminants like pesticides that are not previously associated with marine Atlantic ... -
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 ... -
LC-QTOF MS screening of more than 1,000 licit and illicit drugs and their metabolites in wastewater and surface waters from the area of Bogotá, Colombia
Springer (2015-08)A large screening of around 1,000 emerging contaminants, focused on licit and illicit drugs and their metabolites, has been made in urban wastewaters (both influent and effluent) and surface waters from the area of Bogotá, ... -
Potential of atmospheric pressure chemical ionization source in GC-QTOF MS for pesticide residue analysis
John Wiley & Sons (2010-08)The potential applications of a new atmospheric pressure source for GC-MS analysis have been investigated in this work. A list of around 100 GC-amenable pesticides, which includes organochlorine, organophosphorus and ... -
Quadrupole-time-of-flight mass spectrometry screening for synthetic cannabinoids in herbal blends
John Wiley & Sons (2013-05)‘Legal highs’ are novel substances which are intended to elicit a psychoactive response. They are sold from ‘head shops’, the internet and from street suppliers and may be possessed without legal restriction. Several months ... -
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 ... -
Qualitative Screening of Undesirable Compounds from Feeds to Fish by Liquid Chromatography Coupled to Mass Spectrometry
American Chemical Society (2013)This paper describes the development, validation, and application of a rapid screening method for the detection and identification of undesirable organic compounds in aquaculture products. A generic sample treatment was ... -
Quantification, confirmation and screening capability of UHPLC coupled to triple quadrupole and hybrid quadrupole time-of-flight mass spectrometry in pesticide residue analysis
John Wiley & Sons (2010-04)The potential of three mass spectrometry (MS) analyzers (triple quadrupole, QqQ; time of flight, TOF; and quadrupole time of flight, QTOF) has been investigated and compared for quantification, confirmation and screening ... -
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 ... -
Use of electron ionization and atmospheric pressure chemical ionization in gas chromatography coupled to time-of-flight mass spectrometry for screening and identification of organic pollutants in waters
Elsevier (2014-04)A new approach has been developed for multiclass screening of organic contaminants in water based on the use of gas chromatography coupled to hybrid quadrupole high-resolution time-of-flight mass spectrometry with atmospheric ...
