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 ...
Characterization and hazard identification of substandard and falsified antimicrobials encountered in Belgium
quantification of active pharmaceutical ingredients (API s) potentially present in these suspicious SF antimicrobials, are paramount. Here, a validated ultra-high performance liquid chromatography-tandem mass ...
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 ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
a different toxicological profile, the two fractions were quantified separately using an online combination of liquid chromatography and gas chromatography with flame ionization detection (online LC- GC- FID). ...
DETERMINATION OF ALLERGENIC FRAGRANCE INGREDIENTS IN FEMININE ABSORBENT HYGIENE PRODUCTS AND LUBRICANTS
A liquid-liquid extraction was used as a sample ‘clean-up’ for lubricants. The sample was then injected using gas chromatography-flame ionization-mass spectrometry (GC- FID- MS). The AHP s were analyzed using a HS- ...
Human urine contamination with environmental pollutants: simultaneous determination using UPLC-MS/MS
determine three paraben derivatives: methylparaben (MP), ethylparaben (EP) and propylparaben (PP) using ultra performance liquid chromatography-tandem mass spectrometer (UPLC- MS / MS). The three major ...
