Development and Validation of a UHPLC-ESI-MS/MS Method for Quantification of Oleandrin and Other Cardiac Glycosides and Evaluation of Their Levels in Herbs and Spices from the Belgian Market
develop a targeted analytical method utilizing liquid chromatography—tandem mass spectrometry (LC- MS / MS) for quantification of these plant toxins in a herbal-based food and human urine. The method ...
Biological monitoring of exposure to pesticide residues among Belgian florists
concentrations of pesticide residues and metabolites in urine samples were analyzed with a multiresidue liquid chromatography tandem mass spectrometry method, after an ethyl acetate extraction. The results are ...
The occurrence of putative cognitive enhancing research peptides in seized pharmaceutical preparations: An incentive for controlling agencies to prepare for future encounters of the kind.
findings served as an incentive to develop a novel combined liquid chromatography tandem mass spectroscopy (LC- MS / MS) methodology, applicable to both hydrophilic or more hydrophobic peptides, which was ...
DETERMINATION OF SENSITIZING AND IRRITATING LEACHABLES IN MENSTRUAL HYGIENE PRODUCTS
step and a salting-out assisted liquid-liquid extraction procedure were developed and op-timized. An ultra performance liquid chromatography – triple quad mass spectrometry (UPLC- TQMS) method with a run ...
Weight and head circumference at birth in function of placental paraben load in Belgium: an ENVIRONAGE birth cohort study
propyl (PrP), and butyl (BuP)) were determined by ultra-performance liquid chromatography coupled with tandem mass-spectrometry. Generalized linear regression models were used to determine the association ...
