Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
0.2% m/m, at least for police officers on site. There is a need to characterize these products with a rapid, ecological and cheap analytical method. The current methods of reference are GC- MS, GC- FID ...
Investigation of migrating substances from textile used as food contact material
evaluate the safety of these “new” food fabrics. A simple ultra-sound assisted extraction of substances from the fabrics was done with acetonitrile to avoid any compound losses. Both a GC- MS full scan ...
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 ...

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.

Effect of household and industrial processing on levels of some pesticide residues in carrots
cooking, pasteurization and sterilization) was carried out on industrial pilot scale. Pesticides and the degradation products formed during processing were analyzed with GC – MS / MS and UHPLC – MS / MS. The ...
Identification of potential migrants from printing inks used on paper and board food contact materials
little pieces, then 40 mL acetonitrile was added and the migration was performed at 70°C for 24h. Afterwards, the extracts were analysed using gas chromatography-mass spectrometry (GC- MS n) in full scan ...
