Spectroscopic approaches for conformity analysis of e-liquids
public health. E-liquids typically contain four main ingredients: propylene glycol, glycerin, flavorings and nicotine. The latter is of course not present in zero liquids. The primary issue is the content of ...
Use of near infrared spectroscopy and chemometrics for the classification of different Cannabis spp. samples found in Belgium
of 92 % (for the benchtop) and 93 % (for the handheld device), meaning that 51 of the 56 samples and 52 of 56 samples in the external test set are correctly classified as recreational drug, industrial ...

Environmental Research, Volume 213 (2022) Keywords: Agriculture CHILDREN Green space Mitochondrial DNA content mtDNA Abstract: Background Mitochondria are known to respond to environmental stressors but whether ...
CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up
CBD content not always corresponds to the label claim. There is a pressing need to develop new analytical methods specifically developed to the assay of such oily samples. Analytical issues are, ...
Scientific opinion on the risks for animal and human health related to the presence of quinolizidine alkaloids in feed and food, in particular in lupins and lupin‐derived products
s, the CONTAM Panel used a group approach assuming dose additivity. For food, the highest mean concentration of Total QA s (TotQAs) (i.e. the 6 most abundant QA s) was found in lupin seed samples ...
A comparative study on chemical composition, antibiofilm and biological activities of leaves extracts of four Tunisian olive cultivars
‘Oueslati’ and ‘Jarboui’. By means of standardized methods, total phenols were determined and some of them characterized by HPLC. The total phenols and flavonoids contents were found to be the highest in the ...
Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?
samples of E174 and ten food items containing E174 were investigated for their number-based size distribution of Ag particles. The food items were as well investigated for their total Ag content. Single ...
