Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
genotoxic substances in e-liquid flavours. 77 e-liquids, representative for the different flavour categories, were collected on the Belgian market and screened for their chemical composition using GC- MS. By ...
Ontwikkeling en validatie van een HS-GC-MS/MS methode voor de bepaling van potentieel genotoxische smaakstoffen in e-vloeistoffen.

Plasticizers and bisphenol A, in packaged foods sold in the Tunisian markets: study of their acute in vivo toxicity and their environmental fate.
Then, the identified chemical molecules were studied for their environmental fate and tested in vivo for its toxicity in mice models. The food products analyzed using GC- MS / MS indicated the presence of ...
Risk Assessment of Florists Exposed to Pesticide Residues through Handling of Flowers and Preparing Bouquets.
extracted with a multi-residue Quick Easy Cheap Effective Rugged Safe (QuEChERS) method and analyzed by a combination of gas and liquid chromatography tandem mass spectrometry (GC- MS / MS and LC- MS / MS) by ...
Development and validation of a HS/GC-MS method for the simultaneous analysis of diacetyl and acetylpropionyl in electronic cigarette refills
analytical methods have been published for determining e-liquid compositions, but concerns exist with respect to the lack of analytical evaluation. Hence in this study, a new HS / GC- MS-based method was ...
Identification of a new tert-leucinate class synthetic cannabinoid in powder and "spice-like" herbal incenses: Methyl 2-[[1-(5-fluoropentyl)indole-3-carbonyl]amino]-3,3-dimethyl-butanoate (5F-MDMB-PICA).
chromatography with diode array detector (HPLC- PDA) and gas chromatography mass spectrometry (GC- MS) with computer based library search against spectral libraries. However, the most predominant compound in the ...

Study of the possible migration risks of food contact materials for children under 3 years
dichloromethane (DCM)-n-hexane (1:1 and 1:3). The extracts resulting from the LLE step were analysed on GC-(EI) MS by monitoring specific ions for each analyte and for the internal standard. EtOAc-n-hexane (1:1) ...
Occurrence of polybrominated diphenyl ethers and emerging halogenated flame retardants in food items
performed using gas chromatography-mass spectrometry operated in electron-capture negative ionization mode (GC- ECNI / MS). The validated procedure was first used for the determination of BFR s in 20 ...
A survey of pesticide residues in cut flowers from various countries.
methods (GC- MS- MS and LC- MS- MS) in a laboratory accredited for pesticide residues. For all the samples analysed, a total of 97 active substances were detected, i.e. an average of 14 active substances ...
