Sample preparation methods for elemental analysis in electronic cigarette aerosols: a critical review
impingers, many studies failed to validate critical steps such as aerosol recovery, blank corrections, and the extent of matrix effects. In addition, poor inorganic methodological practices were often applied, ...
Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
Abstract: The detection and quantification of additives in tobacco products are critical for ensuring consumer safety and compliance with regulatory standards. Traditional analytical techniques, like gas ...
Spectroscopic approaches for conformity analysis of e-liquids
issue is the presence of additives, illegal according to the European Directive. Some of the most important are caffeine, taurine and vitamin E. Cannabidiol (CBD), which is in the gray zone of the ...
Development of a “Freeze-Pour” Sample Preparation Method for the GC Analysis of Semivolatile Flavouring Chemicals Present in E-cigarette Refill Liquids
chromatography (HS- GC) analysis is presented as an excellent method for the analysis of high volatile components in e-liquids. For the analysis of semivolatile ingredients, an additional sample preparation step ...
Impact of the revised European Tobacco Product Directive on the quality of e-cigarette refill liquids in Belgium
during (2016) and after (2017-2018) the implementation of the TPD revisions, were analyzed for the presence of nicotine, nicotine-related impurities, volatile organic compounds (VOC s), the additives ...
Genotoxic evaluation of the liquids present in electronic cigarettes
animal-free approaches. In addition, the applicability of the Ames test and the in vitro micronucleus test to evaluate the genotoxic potential of e-liquids mixtures was investigated. [Methods] The study was ...
Chemical characterization of electronic cigarette refills (e-liquids) in Belgium
Tamara; Eric Deconinck Source: 29th International Symposium on Pharmaceutical and Biomedical Analysis, Journal of Pharmaceutical and Biomedical Analysis, Leuven, Belgium (2018) Keywords: additives ...
Identification of Flavouring Substances of Genotoxic Concern Present in E-Cigarette Refills
genotoxic potential. Data for the remaining components was missing or ambiguous and hence additional toxicological data is required in order to be able to exclude genotoxic potential. The above findings ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
glycol, glycerin, flavorings and nicotine, though there have been reports of non-compliant nicotine concentrations and the presence of illegal additives. This study explored spectroscopic techniques to ...
