Analytical methodologies based on LC–MS/MS for monitoring selected emerging compounds in liquid and solid phases of the sewage sludge
Elsevier (2016)In this work, two analytical methodologies based on liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) were developed for quantification of emerging pollutants identified in sewage sludge after a previous ... -
Contributions of MS metabolomics to gilthead sea bream (Sparus aurata) nutrition. Serum fingerprinting of fish fed low fish meal and fish oil diets
Elsevier (2019-01-01)The aim of this study was to evaluate the impact of fish meal (FM) and fish oil (FO) replacement by plant proteins and oils in the serum metabolome of two-year old gilthead sea bream (Sparus aurata) fed from early life ... -
Development and Application of Liquid Chromatographic Retention Time Indices in HRMS-Based Suspect and Nontarget Screening
American Chemical Society (2021)There is an increasing need for comparable and harmonized retention times (tR) in liquid chromatography (LC) among different laboratories, to provide supplementary evidence for the identity of compounds in high-resolution ... -
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 ... -
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 ... -
Evaluation of uncertainty sources in the determination of testosterone in urine by calibration-based and isotope dilution quantification using ultra high performance liquid chromatography tandem mass spectrometry
Elsevier (2017-06)Three quantification methodologies, namely calibration with internal standard (Cal-IS, non-weighted), weighted calibration with internal standard (wCal-IS) and isotope pattern deconvolution (IPD) have been used for the ... -
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 ... -
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 ...
