Determination of free amino acids in plants by liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS)
Royal Society of Chemistry (2015)A robust and sensitive method for identification (quantification and confirmation) of 19 free amino acids in the plant matrix, Stellaria media, based on liquid chromatography-electrospray ionization-tandem mass spectrometry ... -
Investigating the presence of pesticide transformation products in water by using liquid chromatography-mass spectrometry with different mass analyzers
John Wiley & Sons (2008)Many pesticide transformation products (TPs) can reach environmental waters as a consequence of their normally having a higher polarity than their parent pesticides. This makes the development of analytical methodology ... -
Liquid chromatography-tandem mass spectrometry determination of synthetic cathinones and phenethylamines in influent wastewater of eight European cities
Elsevier (2017)The popularity of new psychoactive substances (NPS) has grown in recent years, with certain NPS commonly and preferentially consumed even following the introduction of preventative legislation. With the objective to improve ... -
Multi-class determination of undesirables in aquaculture samples by gas chromatography/tandem mass spectrometry with atmospheric pressure chemical ionization: A novel approach for polycyclic aromatic hydrocarbons
Elsevier (2017)In this work, a method for the analysis of 24 PAHs in 19 different matrices, including fish tissues, feeds and feed ingredients, has been developed using gas chromatography coupled to triple quadrupole tandem mass ... -
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 ... -
Target and non-target screening strategies for organic contaminants, residues and illicit substances in food , environmental and human biological samples by UHPLC-QTOF-MS
RSC Publishing (2012-01)In this paper, we illustrate the potential of ultra-high performance liquid chromatography (UHPLC) coupled with hybrid quadrupole time-of-flight mass spectrometry (QTOF MS) for large scale screening of organic contaminants ... -
