Spectroscopic approaches for conformity analysis of e-liquids

Therefore, it is necessary to monitor the compositions of the products on the market and conduct surveillance studies. In Belgium this is performed under the coordination of the Federal Public Service of ...

Development of vibrational spectroscopic methods combined with chemometrics for the detection and quantification of nicotine in e-liquids.

nicotine-containing e-liquids via the internet. The ban on long-distance sale implies that postal packages containing e-liquids are checked at customs. Furthermore, there is a demand of vapeshop-inspectors for on ...

Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids

is proposed based on a liquid–liquid extraction (LLE) followed by a freeze-out of the matrix components. The developed method was successfully validated in accordance with the validation requirements ...

Identification of flavouring substances of genotoxic concern present in e-cigarette refills

literature data was developed to identify potentially genotoxic e-liquid flavourings. Based on the analysis of 129 e-liquids collected on the Belgian market, 60 flavourings with positive in silico predictions ...

Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium

containing mandatory rules to assure the quality and safety of electronic nicotine delivery systems. In this study, we investigate whether these regulatory changes had an impact on the quality of refill ...

Genotoxic evaluation of the liquids present in electronic cigarettes

2,3-pentanedione). However, for the majority of the compounds, no standard could be obtained and consequently, the Ames test and the in vitro micronucleus test were performed on the e-liquid mixtures. In order to ...

Chemical characterization of electronic cigarette refills (e-liquids) in Belgium
