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 ...
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 ...

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) ...
