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 ... -
Investigation of pharmaceuticals and illicit drugs in waters by liquid chromatography-high-resolution mass spectrometry
Elsevier (2014)Mass spectrometry (MS) coupled to chromatography has been increasingly used in the environmental field, as it allows the best performance currently attainable for the investigation of a wide range of organic pollutants. ... -
Investigation on the consumption of synthetic cannabinoids among teenagers by the analysis of herbal blends and urine samples
Elsevier (2020-04-13)The use of synthetic cannabinoids (SCs), which escape conventional detection systems, may be a good alternative to elude routine drug analysis for cannabis. The detection of these drugs in urine is unusual due to their ... -
Is NMR-based metabolomic analysis of exhaled breath condensate accurate?
Official Scientific Journal of the ERS (2011-02)The metabolomic analysis of exhaled breath condensate (EBC) is a simple noninvasive approach for the study of respiratory system diseases. Previous studies introduced nuclear magnetic resonance (NMR)-based metabolomics as ... -
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 ... -
