Building an empirical mass spectra library for screening of organic pollutants by ultra-high-pressure liquid chromatography/hybrid quadrupole time-of-flight mass spectrometry
(John Wiley, 2011-01-30)
Hybrid quadrupole time-of-flight mass spectrometry (QTOF MS) has gained wide acceptance in many fields of chemistry, for example, proteomics, metabolomics and small molecule analysis. This has been due to the numerous ...
Use of soft and hard ionization techniques for elucidation of unknown compounds by gas chromatography/time-of-flight mass spectrometry
(John Wiley, 2011-05-11)
Investigation of trace-level non-target compounds by gas chromatography/mass spectrometry (GC/MS) often is a challenging task that requires powerful software tools to detect the unknown components, to obtain the deconvoluted ...
Disruption of gut integrity and permeability contributes to enteritis in a fsh‑parasite model: a story told from serum metabolomics
(BMC, 2019)
Background: In the animal production sector, enteritis is responsible for serious economic losses, and intestinal
parasitism is a major stress factor leading to malnutrition and lowered performance and animal production ...
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 ...
Fast determination of 40 drugs in water using large volume direct injection liquid chromatography–tandem mass spectrometry
(Elsevier, 2015)
This work describes a rapid analytical method based on direct sample injection of water samples for the simultaneous identification/quantification of 40 emerging compounds, including pharmaceuticals and drugs of abuse. The ...
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 ...
Occurrence and ecological risks of pharmaceuticals in a Mediterranean river in Eastern Spain
(Elsevier, 2020-11)
Pharmaceuticals are biologically active molecules that may exert toxic effects to a wide range of aquatic organisms. They are considered contaminants of emerging concern due to their common presence in wastewaters and in ...
Investigation of pharmaceutical metabolites in environmental waters by LC-MS/MS
(Springer, 2014)
Pharmaceuticals, once ingested, are commonly metabolized in the body into more polar and soluble forms. These compounds might not be completely removed in the wastewater treatment plants and consequently being discharged ...
Determination of patulin in apple and derived products by UHPLC-MS/MS. Study of matrix effects with atmospheric pressure ionisation sources.
(Elsevier, 2014)
Sensitive and reliable analytical methodology has been developed for the measurement of patulin in regulated foodstuffs by using ultra-high-performance liquid chromatography coupled to tandem mass spectrometry (UHPLC–MS/MS) ...
Improvements in analytical methodology for the determination of frequently consumed illicit drugs in urban wastewater
(Springer, 2014-07)
Rapid and sensitive analytical methodology based on ultra high-performance liquid chromatography-tandem mass spectrometry has been developed for the determination of widely consumed drugs of abuse (amphetamines, MDMA, ...
