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 ...
Screening and quantification of pesticide residues in fruits and vegetables making use of gas chromatography-quadrupole time-of-flight mass spectrometry with atmospheric pressure chemical ionization
(Springer, 2014-11)
An atmospheric pressure chemical ionization source has been used to enhance the potential of gas chromatography coupled with quadrupole time-of-flight (QTOF) mass spectrometry (MS) for screening and quantification purposes ...
Variación en el patrón de consumo de cannabinoides sintéticos de una paciente a lo largo de 2018
(Sociedad Científica Española de Estudios sobre el Alcohol, el Alcoholismo y las otras Toxicomanías, 2020)
El consumo de cannabinoides sintéticos es un problema creciente. En España, el número de incautaciones e intoxicaciones relacionadas con estas nuevas sustancias psicoactivas (NPS) es menor que en el resto de Europa. No ...
Risk assessment for drugs of abuse in the Dutch watercycle
(Elsevier, 2013-04)
A screening campaign of drugs of abuse (DOA) and their relevant metabolites in the aqueous environment was performed in the Netherlands. The presence of DOA, together with the potential risks for the environment and the ...
LC-MS/MS method for the determination of organophosphorus pesticides and their metabolites in salmon and zebrafish fed with plant-based feed ingredients
(Springer, 2019)
The composition of Atlantic salmon feed has changed considerably over the last two decades from being marine-based (fishmeal and fish oil) to mainly containing plant ingredients. Consequently, concern related to traditional ...
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, ...
Development of a fast analytical method for the individual determination of pyrethrins residues in fruits and vegetables by liquid chromatography–tandem mass spectrometry
(Elsevier, 2013-09)
Pyrethrins are natural insecticides derived from chrysanthemum flowers containing a mixture of six components: pyrethrin I, cinerin I, jasmolin I, pyrethrin II, cinerin II, and jasmolin II. In this work, a rapid and sensitive ...
Application of gas chromatography–(triple quadrupole) mass spectrometry with atmospheric pressure chemical ionization for the determination of multiclass pesticides in fruits and vegetables
(Elsevier, 2013-11)
A multi-residue method for the determination of 142 pesticide residues in fruits and vegetables has been developed using a new atmospheric pressure chemical ionization (APCI) source for coupling gas chromatography (GC) to ...
Qualitative validation of a liquid chromatography-quadrupole-time of flight mass spectrometry screening method for organic pollutants in waters
(Elsevier, 2013-02)
A multiclass wide-scope screening of organic contaminants in natural and waste water has been developed and validated for qualitative purposes, i.e. detection and reliable identification of compounds detected in samples ...
The role of GC-MS/MS with triple quadrupole in pesticide residue analysis in food and the environment
(Royal Society of Chemistry, 2013)
Gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) using a triple quadrupole (QqQ) analyzer has in the last few years become a powerful technique for the determination of pesticide residues due to its ...
