Challenges in Drug Surveillance: Strengthening the Analysis of New Psychoactive Substances by Harmonizing Drug Checking Services in Proficiency Testing.
chromatography-mass spectrometry (GC- MS) and liquid chromatography with diode array detector (LC- DAD). RESULTS: The proficiency test scores range from 80 to 97.5% accuracy. The most common issues and errors are ...
Occurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers.
Keywords: beer Belgium DNA Damage Flavoring Agents Gas Chromatography-Mass Spectrometry Abstract: The regulatory landscape of flavorings is evolving, thereby putting pressure on control laboratories to ...
Concentrations and distribution of chlorinated paraffins in Belgian foods
chlorinated paraffins (SCCP s and MCCP s, respectively) in a wide range of food samples (n = 211) purchased in Belgium during 2020. Samples were analysed by gas chromatography-mass spectrometry (GC- MS) and ...
Optimization and validation of an analytical method for the quantification of short- and medium-chained chlorinated paraffins in food by gas chromatography-mass spectrometry
quantification of short- and medium-chained chlorinated paraffins (SCCP s and MCCP s, respectively) in a range of food matrices using gas chromatography-electron capture negative ionization-mass spectrometry (GC ...
Modular Method for the Determination of Polycyclic Aromatic Hydrocarbons in Spices and Dried Herbs by Gas Chromatography–Tandem Mass Spectrometry
s),(benzo[a]anthracene [BaA], chrysene [CHR], benzo[b]fluoranthene [BbF] and benzo[a]pyrene [BaP]), in the wide matrix groupof spices and dried herbs by gas chromatography–tandem mass spectrometry (GC – MS / MS). The ...
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- ...
