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.
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 utilized ...
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 ...
Determination of cardiac glycosides by liquid chromatography-tandem mass spectrometry
Publication Type: Scientific poster, presentation or proceeding Authors: Svetlana V. Malysheva; PPJ Mulder; Julien Masquelier Source: RAFA 2019 (2019) Service: Contaminants organiques et additifs Organische contaminanten en additieven Organic contaminant ...
Analysis of mineral oil in food: An analytical challenge
volatility. Since these two fractions have a different toxicological relevance, it is important to quantify them separately. Commonly, an online technique existing of a combination of Liquid Chromatography with ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography-tandem mass spectrometry
Publication Type: Peer reviewed scientific article Authors: Ilse Van Overmeire; Karen Vrijens; Nawrot, Tim; An Van Nieuwenhuyse; Joris Van Loco; Tim Reyns Source: Journal of Chromatography B, Volume ...
A strategy based on fingerprinting and chemometrics for the detection of regulated plants in plant food supplements from the Belgian market: two case studies
ingredients, though also herbal adulteration occurs and is given less attention. In this paper a two-step approach is presented based on fingerprints recorded by both infrared spectroscopy as liquid ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
characterization of e-liquids of which gas-chromatography is the most often used technique as e-liquids mainly consist out of (semi)-volatile ingredients (i.e. nicotine and flavourings) dissolved in a propylene ...
