Sample preparation methods for elemental analysis in electronic cigarette aerosols: a critical review
selected, a wide variability in sample preparation was observed, specifically variations in aerosol generation characteristics and collection techniques. Despite the widespread use of methods as filters and ...
Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
multivariate analysis, as potential solutions for the detection and quantification of additives in tobacco products. So, a representative set of tobacco products was selected and spiked with the targeted ...
Spectroscopic approaches for conformity analysis of e-liquids
taurine, vitamin E and CBD in e-liquids. Therefore a set of 236 e-liquids was selected. Since samples with caffeine, taurine, CBD and vitamin E as additives were hard to find, some of the samples were split ...
Identification of flavouring substances of genotoxic concern present in e-cigarette refills
transhexanal, there was a clear concern for in vivo genotoxicity. A selection of 4 out of the remaining 22 flavourings was tested in two in vitro genotoxicity assays. Three out of the four tested flavourings ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
flavourings diacetyl and acetylpropionyl. The low and semi-volatiles contain potential genotoxic flavourings, selected through in-silico genotoxicity screening of 436 identified components in 77 e-liquid ...
Genotoxic evaluation of the liquids present in electronic cigarettes
models and the availability of genotoxicity data, 28 compounds detected in e-liquids were selected for in vitro genotoxicity testing. However, only two of these compounds were commercially available. ...
Spectroscopy and Chemometrics for Conformity Analysis of e-Liquids: Illegal Additive Detection and Nicotine Characterization
carefully selected for analysis. Chemometric analysis was applied to the collected data, which included mid-infrared (MIR) and near-infrared (NIR) spectra. Supervised modeling approaches such as partial least ...
