Chromatography hyphenated to high resolution mass spectrometry in untargeted metabolomics for investigation of food (bio)markers
Elsevier (2021-02-01)Currently, there is a growing demand by our society, authorities and science to increase the knowledge about the quality of food and its relationship with health and disease. Untargeted metabolomics approaches are emerging ... -
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 ... -
Current use of high-resolution mass spectrometry in the environmental sciences
Springer (2012-05)During the last two decades, mass spectrometry (MS) has been increasingly used in the environmental sciences with the objective of investigating the presence of organic pollutants. MS has been widely coupled with chromatographic ... -
Efficient Validation Strategies in Environmental Analytical Chemistry: A Focus on Organic Micropollutants in Water Samples
Annual Reviews (2023)This article critically reviews analytical method validation and quality control applied to the environmental chemistry field. The review focuses on the determination of organic micropollutants (OMPs), specifically emerging ... -
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 ... -
Isotope Dilution LC-ESI-MS/MS and low resolution Selected Reaction Monitoring as a tool for the accurate quantification of urinary testosterone
Elsevier (2018-09)A new analytical method for the quantification of testosterone in human urine samples by isotope dilution mass spectrometry is proposed. A standard solution of 13C2-testosterone is added to the samples at the beginning of ... -
Mass spectrometric characterisation of acondensation product betweenporphobilinogen and indolyl-3-acryloylglycinein urine of patients with acuteintermittent porphyria
Wiley (2015-07)We document the presence of a previously unknown species in the urine of patients with acute intermittent porphyria (AIP). Thecompound was fully characterised by liquid chromatography tandem mass spectrometry. Interpretation ... -
Monitoring new psychoactive substances use through wastewater analysis: current situation, challenges and limitations
Elsevier (2019-06)New psychoactive substances (NPSs) are compounds that produce similar effects to those induced by illicit drugs (IDs), such as cocaine, cannabis, and amphetamines, but are not strictly regulated by international conventions. ... -
Perspectives and challenges associated with the determination of new psychoactive substances in urine and wastewater – A tutorial
Elsevier (2021-02-08)New psychoactive substances (NPS), often designed as (legal) substitutes to conventional illicit drugs, are constantly emerging in the drug market and being commercialized in different ways and forms. Their use continues ... -
Prediction of Collision Cross-Section Values for Small Molecules: Application to Pesticide Residue Analysis
(2017)The use of collision cross-section (CCS) values obtained by ion mobility high-resolution mass spectrometry has added a third dimension (alongside retention time and exact mass) to aid in the identification of compounds. ... -
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 ... -
Quality classification of Spanish olive oils by untargeted gas chromatography coupled to hybrid quadrupole–time of flight mass spectrometry with atmospheric pressure chemical ionization and metabolomics-based statistical approach
Elsevier (2017-02)The novel atmospheric pressure chemical ionization (APCI) source has been used in combination with gas chromatography (GC) coupled to hybrid quadrupole time-of-flight (QTOF) mass spectrometry (MS) for determination of ... -
